Bourjaily, Einan Gardi, Andrew J. McLeod, and Cristian Vergu Categories: hep-th Comments: 49 pages, 8 figures \\ We explore the correspondence between one-loop Feynman integrals and (hyperbolic) simplicial geometry to describe the "all-mass" case: integrals with generic external and internal masses. Specifically, we focus on $n$-particle integrals in exactly $n$ space-time dimensions, as these integrals have particularly nice geometric properties and respect a dual conformal symmetry. In four dimensions, we leverage this geometric connection to give a concise dilogarithmic expression for the all-mass box in terms of the Murakami-Yano formula. In five dimensions, we use a generalized Gauss-Bonnet theorem to derive a similar dilogarithmic expression for the all-mass pentagon. We also use the Schl\"afli formula to write down the symbol of these integrals for all $n$. Finally, we discuss how the geometry behind these formulas depends on space-time signature, and we gather together many results related to these integrals from the mathematics and physics literature. \\ ( https://arxiv.org/abs/1912.11067 , 385kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11068 Date: Mon, 23 Dec 2019 19:16:14 GMT (205kb,D) Title: Numerical Metrics, Curvature Expansions and Calabi-Yau Manifolds Authors: Wei Cui and James Gray Categories: hep-th Comments: 14 pages, 8 figures \\ We discuss the extent to which numerical techniques for computing approximations to Ricci-flat metrics can be used to investigate hierarchies of curvature scales on Calabi-Yau manifolds. Control of such hierarchies is integral to the validity of curvature expansions in string effective theories. Nevertheless, for seemingly generic points in moduli space it can be difficult to analytically determine if there might be a highly curved region localized somewhere on the Calabi-Yau manifold. We show that numerical techniques are rather efficient at deciding this issue. \\ ( https://arxiv.org/abs/1912.11068 , 205kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11075 Date: Sat, 26 Oct 2019 22:30:19 GMT (342kb,D) Title: Phase Transition of AdS Black hole in Massive Gravity Revisited via New Prescription Authors: M.

Helay\"el-Neto Categories: hep-th Comments: 5 pages \\ Aspects of screening and confinement are re-examined for a recently proposed compact Abelian Higgs model with a $\theta$-term. Our discussion is accomplished using the gauge-invariant but path-dependent variables formalism, which is an alternative to the Wilson loop approach. We explicitly show that the static potential profile is the sum of an effective-Yukawa and a linear potential, leading to the confinement of static external charges. We point out the central r\^ole of the parameter measuring the stiffness of the vortex lines present in the model in both the Yukawa-like and the confining sectors of the effective inter-particle potential we have computed. \\ ( https://arxiv.org/abs/1912.11091 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11100 Date: Mon, 23 Dec 2019 20:38:22 GMT (532kb,D) Title: Nonperturbative Mellin Amplitudes: Existence, Properties, Applications Authors: Joao Penedones, Joao A. Silva, Alexander Zhiboedov Categories: hep-th Comments: 117 pages, 23 figures \\ We argue that nonperturbative CFT correlation functions admit a Mellin amplitude representation. Perturbative Mellin representation readily follows. We discuss the main properties of nonperturbative CFT Mellin amplitudes: subtractions, analyticity, unitarity, Polyakov conditions and polynomial boundedness at infinity. Mellin amplitudes are particularly simple for large N CFTs and 2D rational CFTs. We discuss these examples to illustrate our general discussion. We consider subtracted dispersion relations for Mellin amplitudes and use them to derive bootstrap bounds on CFTs. We combine crossing, dispersion relations and Polyakov conditions to write down a set of extremal functionals that act on the OPE data. We check these functionals using the known 3d Ising model OPE data and other known bootstrap constraints. We then use them to constrain holographic theories. To our great surprise, we find that a free massive scalar minimally coupled to gravity does not admit UV completion as a consistent theory of quantum gravity within a certain range of masses! \\ ( https://arxiv.org/abs/1912.11100 , 532kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11161 Date: Tue, 24 Dec 2019 01:07:31 GMT (115kb,D) Title: Higher-Derivative Corrections to Entropy and the Weak Gravity Conjecture in Anti-de Sitter Space Authors: Sera Cremonini, Callum R. T. Jones, James T. Liu and Brian McPeak Categories: hep-th Comments: 57 pages \\ We compute the four-derivative corrections to the geometry, extremality bound, and thermodynamic quantities of AdS-Reissner-Nordstr{\"o}m black holes for general dimensions and horizon geometries. We confirm the universal relationship between the extremality shift at fixed charge and the shift of the microcanonical entropy, and discuss the consequences of this relation for the Weak Gravity Conjecture in AdS. The thermodynamic corrections are calculated using two different methods: first by explicitly solving the higher-derivative equations of motion and second, by evaluating the higher-derivative Euclidean on-shell action on the leading-order solution. In both cases we find agreement, up to the addition of a Casimir energy in odd dimensions. We derive the bounds on the four-derivative Wilson coefficients implied by the conjectured positivity of the leading corrections to the microcanonical entropy of thermodynamically stable black holes. These include the requirement that the coefficient of Riemann-squared is positive, meaning that the positivity of the entropy shift is related to the condition that $c - a$ is positive in the dual CFT. We discuss implications for the deviation of $\eta/s$ from its universal value and a potential lower bound. \\ ( https://arxiv.org/abs/1912.11161 , 115kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11201 Date: Tue, 24 Dec 2019 04:32:00 GMT (2582kb,D) Title: Entanglement branes and factorization in conformal field theory Authors: Ling Yan Hung, Gabriel Wong Categories: hep-th gr-qc math-ph math.MP quant-ph Comments: 26 pages, 10 figures \\ In this work, we consider the question of local Hilbert space factorization in 2D conformal field theory in the presence of a Kac-Moody symmetry. Generalizing previous work on entanglement and open-closed TQFT, we interpret the factorization of CFT states in terms of path integral processes that split and join the Hilbert spaces of circles and intervals. More abstractly, these processes are cobordisms of an extended CFT which are defined purely in terms of the OPE data. In addition to the usual sewing axioms, we impose an entanglement boundary condition that is solved by the vacuum Ishibashi state. This choice of entanglement boundary state leads to reduced density matrices that sum over super-selection sectors, which we identify as the CFT edge modes. Finally, we relate our factorization map to the co-product formula for the Kac-Moody algebra, which we show is equivalent to a Boguliubov transformation in the case of a free boson. \\ ( https://arxiv.org/abs/1912.11201 , 2582kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11224 Date: Tue, 24 Dec 2019 06:42:22 GMT (100kb,D) Title: Emergent Dark Matter and Dark Energy from a Lattice Model Authors: Luis Lozano, Hugo Garcia-Compean Categories: hep-th cond-mat.other gr-qc math-ph math.MP Comments: 17 pages, 6 figures \\ We propose a quantum bosonic qubit model on a fcc lattice to obtain mimetic dark matter. The general relativity contribution is implemented very similar to other works but it differs strongly on the implementation of the constraint equations and their meaning. Different mimetic theories are implemented starting with the mimetic dark matter, the vector mimetic dark mater, and tensor-vector-scalar models. In all these cases, a generalized Gauss' law incorporates an additional topological defect depending on the type of generalization, but always fitting in the structure of the topological defects from general relativity contribution. \\ ( https://arxiv.org/abs/1912.11224 , 100kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11277 Date: Tue, 24 Dec 2019 10:19:04 GMT (177kb,D) Title: Magneto-vortical effect in strongly coupled plasma Authors: Yanyan Bu and Shu Lin Categories: hep-th hep-ph nucl-th Comments: 37 pages, 6 figures \\ Based on a holographic model incorporating both chiral anomaly and gravitational anomaly, we study the effect of magneto-vortical coupling on transport properties of a strongly coupled plasma. The focus of present work is on the generation of a vector charge density and an axial current, as response to vorticity in a magnetized plasma. The transport coefficients parameterising the vector charge density and axial current are calculated both analytically (in the weak magnetic field limit) and also numerically (for general values of the magnetic field). We find the generation of vector charge receives both non-anomalous and anomalous contributions, with the non-anomalous contribution dominating in the limit of strong magnetic field and the anomalous contribution sensitive to both chiral anomaly and gravitational anomaly. On the contrary, we find the axial current is induced entirely due to the gravitational anomaly, thus we interpret the axial current generation as chiral vortical effect. The corresponding chiral vortical conductivity is found to be suppressed by the magnetic field. By Onsager relation, these transport coefficients are responsible for the generation of a thermal current due to a transverse electric field or a transverse axial magnetic field, which we call thermal Hall effect and thermal axial magnetic effect, respectively. \\ ( https://arxiv.org/abs/1912.11277 , 177kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11282 Date: Tue, 24 Dec 2019 10:32:16 GMT (17kb) Title: SO(9) characterisation of the Standard Model gauge group Authors: Kirill Krasnov Categories: hep-th hep-ph Comments: 18 pages \\ A recent series of works by M. Dubois-Violette, I. Todorov and S. Drenska characterised the SM gauge group as the subgroup of SO(9) that, in the octonionic model of the later, preserves the split of the space of octonions into a copy of the complex plane plus the rest. This description, however, proceeded via the exceptional Jordan algebra J_3^8 and its group of automorphisms F_4, and remained rather indirect. The goal of this paper is to provide as explicit description as possible and also clarify the underlying geometry. It is well-known that the groups SO(3), SO(5) and SO(9) have a complex, quaternionic and octonionic models respectively. The first of these is the familiar realisation of the (double cover of) the rotation group in three dimensions in terms of 2x2 special unitary matrices. Replacing complex numbers with quaternions and octonions one gets SO(5) and SO(9) respectively. Choosing a unit imaginary quaternion or octonion then equips quaternions or octonions with an almost complex structure, and thus introduces the splits H=C+C or O=C+C^3, where the first copy of C is the one containing the imaginary unit that generates the almost complex structure. The subgroup of transformations in SO(5) that preserves H=C+C is SU(2)xU(1)/Z_2. The subgroup of transformations in SO(9) that preserves the split C=C+C^3 is the Standard Model gauge group SU(3)xSU(2)xU(1)/Z_6. We explain all these statements, as well as work out their analogs for the split quaternions and octonions. \\ ( https://arxiv.org/abs/1912.11282 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11296 Date: Tue, 24 Dec 2019 11:21:55 GMT (13kb,D) Title: Induced cosmological and Newton constants from towers of states Authors: Herv\'e Partouche, Balthazar de Vaulchier Categories: hep-th gr-qc Comments: Based on a talk given at the Corfu Summer Institute 2019 "School and Workshops on Elementary Particle Physics and Gravity'' (CORFU2019), 31 August -- 25 September 2019, Corfu, Greece \\ We consider quadratic gravity with only Ricci squared and Weyl squared kinetic terms at tree-level, coupled to specific numbers of infinite towers of free scalars, Weyl fermions and gauge bosons in four dimensions.

The induced metric on brane corresponds to an exact FLRW geometry, while the evolution of brane is determined by Israel junction condition and the effective Einstein field equation on brane together. When the brane approaches the AdS boundary, AdS/CFT correspondence implies that a radiation dominated FLRW-universe ($P=\frac{1}{3}\rho$) should be given. According to the holographic renormalization procedure, we involve an appropriate surface counterterm into the gravitational action for achieving $P=\frac{1}{3}\rho$ on brane. This surface counterterm also plays a important role in caculating the mass of charged AdS dilaton black hole. Finally, we obtain the thermodynamic quantities and give an extend Cardy-Verlinde formula on brane. \\ ( https://arxiv.org/abs/1912.11319 , 413kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11321 Date: Tue, 24 Dec 2019 12:41:30 GMT (5638kb,D) Title: Abelian Chern-Simons vortices at finite chemical potential Authors: S. Prem Kumar and Stanislav Stratiev Categories: hep-th Comments: 22 pages, 12 figures \\ We examine vortices in Abelian Chern-Simons theory coupled to a relativistic scalar field with a chemical potential for particle number or U(1) charge. The Gauss constraint requires chemical potential for the local symmetry to be accompanied by a constant background charge density/magnetic field. Focussing attention on power law scalar potentials $\sim|\Phi|^{2s}$ which do not support vortex configurations in vacuum but do so at finite chemical potential, we numerically study classical vortex solutions for large winding number |n| >> 1. The solutions depending on a single dimensionless parameter $\alpha$, behave as uniform incompressible droplets with radius $\sim \sqrt {\alpha |n|}$ , and energy scaling linearly with |n|, independent of coupling constant. In all cases, the vortices transition from type I to type II at a critical value of the dimensionless parameter, $\alpha_c = s/(s-1)$, which we confirm with analytical arguments and numerical methods. \\ ( https://arxiv.org/abs/1912.11321 , 5638kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11390 Date: Tue, 24 Dec 2019 14:54:14 GMT (741kb,D) Title: Gauge-invariant spectral description of the $U(1)$ Higgs model from local composite operators Authors: David Dudal, Duive Maria van Egmond, Marcelo Santos Guimaraes, Ozorio Holanda, Leticia F.

These operators enable us to give a gauge-invariant description of the spectrum of the theory, thereby surpassing certain incommodities when using the standard elementary fields. The corresponding two-point correlation functions are evaluated at one-loop order and their spectral functions are obtained explicitly. As expected, the above mentioned correlation functions are independent from the gauge parameter $\xi$, while exhibiting positive spectral densities as well as gauge-invariant pole masses corresponding to the massive photon and Higgs physical excitations. \\ ( https://arxiv.org/abs/1912.11390 , 741kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11422 Date: Tue, 24 Dec 2019 15:59:06 GMT (370kb) Title: Hidden Analytic Structure of Higgs Amplitudes and Maximal Transcendentality Principle Authors: Qingjun Jin and Gang Yang Categories: hep-th hep-ph Comments: 11 pages, 2 figures; Proceedings of the 14th International Symposium on Radiative Corrections (RADCOR2019) 9-13 September 2019, Avignon, France Journal-ref: PoS(RADCOR2019)071 \\ We present the computation of two-loop Higgs plus three-parton amplitudes with dimension-seven operators in Higgs effective field theory. The computation is based on the combination of unitarity cut and integration by parts methods in an unconventional way. The analytic results take remarkably simple form. In particular, the results show that the QCD and N=4 SYM results share the same leading transcendental parts. This generalizes the so-call maximal transcendentality principle to the Higgs amplitudes with high dimension operators and also with fundamental external quark states. Further simplicity also exists in lower transcendental parts, suggesting hidden structures beyond maximal transcendentality. \\ ( https://arxiv.org/abs/1912.11422 , 370kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11454 Date: Tue, 24 Dec 2019 18:05:22 GMT (2114kb) Title: On-shell Methods for Form Factors in N=4 SYM and Their Applications Authors: Gang Yang Categories: hep-th Comments: 56 pages, 20 figures; invited review for Science China Physics, Mechanics & Astronomy \\ Form factors are quantities that involves both asymptotic on-shell states and gauge invariant operators. They provide a natural bridge between on-shell amplitudes and off-shell correlation functions of operators, thus, allow us to use modern on-shell amplitude techniques to probe into the off-shell side of quantum field theory. In particular, form factors have been successfully used in computing the cusp (soft) anomalous dimensions and anomalous dimensions of general local operators. This review is intended to provide a pedagogical introduction to some of these developments. We will first review some amplitudes background using four-point amplitudes as main examples. Then we generalize these techniques to form factors, including (1) tree-level form factors, (2) Sudakov form factor and infrared singularities, (3) form factors of general operators and their anomalous dimensions. Although most examples we consider are in N=4 super-Yang-Mill theory, the on-shell methods are universal and are expected to be applicable to general gauge theories. \\ ( https://arxiv.org/abs/1912.11454 , 2114kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11461 Date: Tue, 24 Dec 2019 18:33:29 GMT (28kb) Title: The correlation function of (1,1) and (2,2) supersymmetric theories with $T\bar{T}$ deformation Authors: Song He, Jia-Rui Sun, Yuan Sun Categories: hep-th \\ In the paper, based on recent studies on $T\bar{T}$ deformation of 2D field theory with supersymmetry, we investigate the deformed correlation functions in $\mathcal{N}=(1,1)$ and $\mathcal{N}=(2,2)$ 2D superconformal field theories. Up to the leading order in perturbation theory, we compute the correlation functions under $T\bar{T}$ deformation. The correlation functions in these undeformed theories are almost known, and together with the help of superconformal Ward identity in $\mathcal{N}=(1,1)$ and $\mathcal{N}=(2,2)$ theories respectively we can obtain the correlation functions with operator $T\bar{T}$ inserted. Finally, by employing dimensional regularization, we can work out the integrals in the first order perturbation. The study in this paper extends previous works on the correlation functions of $T\bar{T}$ deformed bosonic CFT to the supersymmetric case. \\ ( https://arxiv.org/abs/1912.11461 , 28kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11471 Date: Tue, 24 Dec 2019 18:53:05 GMT (70kb,D) Title: Double-Janus Linear Sigma Models and Generalized Reciprocity for Gauss Sums Authors: Ori J. Ganor, Hao-Yu Sun, Nesty R. Torres-Chicon Categories: hep-th math.NT Comments: 60 pages, 1 figure \\ We study the supersymmetric partition function of a 2d linear $\sigma$-model whose target space is a torus with a complex structure that varies along one worldsheet direction and a K\"ahler modulus that varies along the other. This setup is inspired by the dimensional reduction of a Janus configuration of 4d $\mathcal{N}=4$ $U(1)$ Super-Yang-Mills theory compactified on a mapping torus ($T^2$ fibered over $S^1$) times a circle with an $SL(2,\mathbb{Z})$ duality wall inserted on $S^1$, but our setup has minimal supersymmetry. The partition function depends on two independent elements of $SL(2,\mathbb{Z})$, one describing the duality twist, and the other describing the geometry of the mapping torus. It is topological and can be written as a multivariate quadratic Gauss sum. By calculating the partition function in two different ways, we obtain identities relating different quadratic Gauss sums, generalizing the {\it Landsberg-Schaar} relation. These identities are a subset of a collection of identities discovered by F. Deloup. Each identity contains a phase which is an eighth root of unity, and we show how it arises as a Berry phase in the supersymmetric Janus-like configuration. Supersymmetry requires the complex structure to vary along a semicircle in the upper half-plane, as shown by Gaiotto and Witten in a related context, and that semicircle plays an important role in reproducing the correct Berry phase. \\ ( https://arxiv.org/abs/1912.11471 , 70kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1912.02609 (*cross-listing*) Date: Sat, 30 Nov 2019 11:12:36 GMT (27kb) Title: Cauchy problem and strong necessary conditions Authors: {\L}ukasz T.

In this paper, we analytically compute the three particle correlator in the collinear limit in QCD for quark and gluon jets, and also in $\mathcal{N}=4$ super Yang-Mills theory. We find an intriguing duality between the integrals for the energy correlators and infrared finite Feynman parameter integrals, which maps the angles of the correlators to dual momentum variables. In $\mathcal{N}=4$, we use this duality to express our result as a rational sum of simple Feynman integrals (triangles and boxes). In QCD our result is expressed as a sum of the same transcendental functions, but with more complicated rational functions of cross ratio variables as coefficients. Our results represent the first analytic calculation of a three-prong jet substructure observable of phenomenological relevance for the LHC, revealing unexplored simplicity in the energy flow of QCD jets. They also provide valuable data for improving the understanding of the light-ray operator product expansion. \\ ( https://arxiv.org/abs/1912.11050 , 2324kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11053 (*cross-listing*) Date: Mon, 23 Dec 2019 19:00:03 GMT (996kb,D) Title: Radion-Activated Higgs Mechanism Authors: Cem Er\"oncel, Jay Hubisz, Gabriele Rigo Categories: hep-ph hep-th Comments: 35 pages, 9 figures Report-no: DESY 19-236 \\ We study multi-scalar models of radius stabilization, with an eye towards application to novel extra-dimensional models of symmetry breaking. With inspiration from holography, we construct a multi-scalar effective potential that is a function of UV-brane values of the scalar fields, and that takes into account bulk gravitational backreaction. We study extrema of this potential, and additionally provide a "superpotential" method for generating static solutions for the extra-dimensional geometry. We apply these methods to some simple models of the Higgs mechanism where the Higgs itself plays a non-trivial role in radius stabilization. We note that tuning of the Higgs mass relative to the Kaluza-Klein scale is related to various types of tuning of 5D parameters, with different resulting spectra and phenomenologies. \\ ( https://arxiv.org/abs/1912.11053 , 996kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11063 (*cross-listing*) Date: Mon, 23 Dec 2019 19:02:40 GMT (1028kb,D) Title: Does scrambling equal chaos?

Indeed, scrambling can simply result from the presence of unstable fixed points in phase space, even in an integrable model. We derive a lower bound on the OTOC Lyapunov exponent which depends only on local properties of such fixed points. We present several models for which this bound is tight, i.e. for which scrambling is dominated by the local dynamics around the fixed points. We propose that the notion of scrambling be distinguished from that of chaos. \\ ( https://arxiv.org/abs/1912.11063 , 1028kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11102 (*cross-listing*) Date: Mon, 23 Dec 2019 20:48:47 GMT (28kb) Title: Energy inequalities in interacting quantum field theories Authors: Daniela Cadamuro Categories: math-ph hep-th math.MP Comments: to appear in the proceedings of the conference "Progress and Visions in Quantum Theory in View of Gravity - Bridging Foundations of Physics and Mathematics", Leipzig 2018; 8 pages MSC-class: 81T05 (primary), 81T40 (secondary) \\ The classical energy conditions, originally motivated by the Penrose-Hawking singularity theorems of general relativity, are violated by quantum fields.

Assumption of condensation for the spinor field simplifies the homogeneous solution of the Dirac equations and connects the spinor field with the scale parameter of the universe. Potentials which allow for a slow-roll dynamics yield new inflationary scenarios with initial de Sitter behavior. Investigating the scenario at the perturbation level gives the scalar spectral index and tensor-to-scalar ratio in agreement with Planck observations: As an example $V(\psi) = V_0 \exp \left[ \xi \log^{-1}|\bar{\psi}\psi|\right]$ gives $r \sim 10^{-4}$ and $n_s \sim 0.967$. The efficiency of inflation from fermions reveals the capabilities of the scenario and makes it a good candidate for the description of nature. \\ ( https://arxiv.org/abs/1912.11124 , 150kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11195 (*cross-listing*) Date: Tue, 24 Dec 2019 03:48:22 GMT (20kb) Title: $\mathbb{Z}_2^n$-Graded extensions of supersymmetric quantum mechanics via Clifford algebras Authors: N.

Tadpoles (short loops) behave nontrivially under gluing and play a crucial role in the result. \\ ( https://arxiv.org/abs/1912.11202 , 71kb) ------------------------------------------------------------------------------ \\ arXiv:1912.11433 (*cross-listing*) Date: Tue, 24 Dec 2019 16:48:13 GMT (24kb) Title: The BFK-gluing formula and the curvature tensors on a 2-dimensional compact hypersurface Authors: Klaus Kirsten and Yoonweon Lee Categories: math.DG hep-th math-ph math.MP math.SP Comments: 28 pages MSC-class: 58J20 \\ In the proof of the BFK-gluing formula for zeta-determinants of Laplacians there appears a real polynomial whose constant term is an important ingredient in the gluing formula. This polynomial is determined by geometric data on an arbitrarily small collar neighborhood of a cutting hypersurface. In this paper we express the coefficients of this polynomial in terms of the scalar and principal curvatures of the cutting hypersurface embedded in the manifold when this hypersurface is 2-dimensional. Similarly, we express some coefficients of the heat trace asymptotics of the Dirichlet-to-Neumann operator in terms of the scalar and principal curvatures of the cutting hypersurface. \\ ( https://arxiv.org/abs/1912.11433 , 24kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1707.03694 replaced with revised version Tue, 24 Dec 2019 00:02:42 GMT (23kb) Title: Lorentz symmetry breaking in a Yang-Mills theory within the Gribov restriction Authors: D.
