On the Solution of Boundary Value Problems Set in Domains With Moving Boundaries

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 10, Page 10427-10441, 15 July 2025.
ABSTRACT We construct solutions for time‐dependent boundary value problems set in moving domains with Dirichlet, Neumann, and mixed boundary conditions. When the boundaries are time deformations of an initial boundary along a vector field, we can refer the boundary problem to a fixed domain at the cost of increasing the complexity of the coefficients ...

A Space-Time Discontinuous Galerkin Trefftz Method for time dependent Maxwell's equations

open access: yes, 2014
We consider the discretization of electromagnetic wave propagation problems by a discontinuous Galerkin Method based on Trefftz polynomials. This method fits into an abstract framework for space-time discontinuous Galerkin methods for which we can prove ...

Calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling with spectral method

open access: yesФизика волновых процессов и радиотехнические системы, 2013
By the means of spectral method the universal algorithm of calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling is presented. The method is based upon presenting of guiding structures fields as serial expansion

A free boundary problem with convection for the p-Laplacian [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1997
We prove existence of weak solutions for a Stefan-type initial value problem with prescribed convection, generalizing previous results to the case of the p-Laplacian.

Totally Volume Integral of Fluxes for Discontinuous Galerkin Method (TVI-DG) I-Unsteady Scalar One Dimensional Conservation Laws

open access: yesمجلة المختار للعلوم, 2017
The volume integral of Riemann flux in the discontinuous Galerkin (DG) method is introduced in this paper. The boundaries integrals of the fluxes (Riemann flux) are transformed into volume integral.
