Elliptic Curves, Algebraic Geometry Approach in Gravity Theory and Uniformization of Multivariable Cubic Algebraic Equations
Bogdan G. Dimitrov
Based on the distinction between the covariant and contravariant metric tensor components in the framework of the affine geometry approach and the s.c. "gravitational theories with…
Surface modes and photonic modes in Casimir calculations for a compact cylinder
V. V. Nesterenko
A rigorous formulation of the problem of calculating the electromagnetic vacuum energy of an infinite dielectric cylinder is discussed. It is shown that the physically relevant spe…
Entanglement Entropy in Quantum Gravity and the Plateau Problem
Dmitri V. Fursaev
In a quantum gravity theory the entropy of entanglement between the fundamental degrees of freedom spatially divided by a surface is discussed. The classical gravity is conside…
A Note on the Viability of Gauss-Bonnet Cosmology
R. Chingangbam, M. Sami, P. V. Tretyakov +1
In this paper, we analyze the viability of a vacuum Gauss-Bonnet cosmology by examining the dynamics of the homogeneous and anisotropic background in 4+1 dimensions. The trajectori…
Gauge theory in deformed N=(1,1) superspace
I. L. Buchbinder, E. A. Ivanov, O. Lechtenfeld +2
We review the non-anticommutative Q-deformations of N=(1,1) supersymmetric theories in four-dimensional Euclidean harmonic superspace. These deformations preserve chirality and har…
Operator approach to analytical evaluation of Feynman diagrams
A. P. Isaev
The operator approach to analytical evaluation of multi-loop Feynman diagrams is proposed. We show that the known analytical methods of evaluation of massless Feynman integrals, su…
