Constant-Sign Green’s Function of a Second-Order Perturbed Periodic Problem
Axioms, 2022 In this paper, we were interested in obtaining the exact expression and studying the regions of constant sign of Green’s function related to a second-order perturbed periodic problem coupled with integral boundary conditions at the extremes of the ...

Periodic boundary conditions and G 2 cosmology
Classical and Quantum Gravity, 2023 Abstract In the standard concordance cosmology the spatial curvature is assumed to be constant and zero (or at least very small). In particular, in numerical computations of the structure of the Universe using N-body simulations, exact periodic boundary conditions are assumed which constrains the spatial curvature.

Monotone iterative technique for fractional differential equations with periodic boundary conditions [PDF]
Opuscula Mathematica, 2009 In this paper we develop Monotone Method using upper and lower solutions for fractional differential equations with periodic boundary conditions. Initially we develop a comparison result and prove that the solution of the linear fractional differential ...

Rotational Bloch Boundary Conditions and the Finite-Element Implementation in Photonic Devices
Photonics, 2023 This article described the implementation of rotational Bloch boundary conditions in photonic devices using the finite element method (FEM). For the electromagnetic analysis of periodic structures, FEM and Bloch boundary conditions are now widely used ...

Effects of a Finite Volume in the Phase Structure of QCD
Universe, 2022 Working in the SU(2) flavor version of the NJL model, we study the effect of taking a finite system volume on a strongly interacting system of quarks, and, in particular, the location of the chiral phase transition and the CEP. We consider two shapes for

Ergodic problems and periodic homogenization for fully nonlinear equations in half-space type domains with Neumann boundary conditions [PDF]
, 2008 We study periodic homogenization problems for second-order pde in half-space type domains with Neumann boundary conditions. In particular, we are interested in "singular problems" for which it is necessary to determine both the homogenized equation and ...
