Large Order Behavior of Quasiclassical Euclidean Gravity in Minisuperspace Models [PDF]

, 1996
We demonstrate in two minisuperspace models that a perturbation expansion of quasiclassical Euclidean gravity has a factorial dependence on the order of the term at large orders. This behavior indicates that the expansion is an asymptotic series which is

Classical and Mild Solution of the First Mixed Problem for the Telegraph Equation with a Nonlinear Potential

Известия Иркутского государственного университета: Серия "Математика", 2023
We study the first mixed problem for the telegraph equation with a nonlinear potential in the first quadrant. We pose the Cauchy conditions on the lower base of the domain and the Dirichlet condition on the lateral boundary.

Space-time noncommutativity and (1+1) Higgs Model

, 2003
We compare the classical scattering of kinks in (1+1) Higgs model with its analogous noncommutative counterpart. While at a classical level we are able to solve the scattering at all orders finding a smooth solution, at a noncommutative level we present ...

On Hyperbolic Equations with a Translation Operator in Lowest Derivatives

Mathematics
In the half-plane, a solution to a two-dimensional hyperbolic equation with a translation operator in the lowest derivative with respect to a spatial variable varying along the entire real axis is constructed in an explicit form.

Solution of nonlocal boundary value problems for the heat equation with discontinuous coefficients, in the case of two discontinuity points

Қарағанды университетінің хабаршысы. Математика сериясы
In this paper, the solution of the initial-boundary value problem for the heat equation with a discontinuous coefficient under periodic or antiperiodic boundary conditions in the case of two discontinuity points is substantiated using the method of ...

Solution of classical stochastic one dimensional many-body systems

, 1999
We propose a simple method that allows, in one dimension, to solve exactly a wide class of classical stochastic many-body systems far from equilibrium.

Classical solutions of higher-derivative theories [PDF]

Physics Letters B, 2013
We present exact classical solutions of the higher-derivative theory that describes the dynamics of the position modulus of a probe brane within a five-dimensional bulk. The solutions can be interpreted as static or time-dependent throats connecting two parallel branes.
