In this study,we develop a new finite difference method,which use not only displacement but also its gradients,to solve the acoustic and elastic wave equati
We consider the stationary and the non stationary Stokes equations with nonstandard boundary conditions where the pressure and the tangential velocity are i
We shall report the recent results of the quasi-neutral limit of the full Navier-Stokes-Poisson system for both strong solution and weak solutions.In partic
After reviewing the theory of singular limits of smooth solutions of evolutionary partial differential equations both for the standard case in which the lar
Formulating a Schubert problem as the solutions to a system of equations in either Pluecker space or in the local coordinates of a Schubert cell typically i
We carry out Lie group classification of a generalized coupled(2+1)-dimensional hyperbolic system.Several cases arise for which the Principal Lie algebra ex
We study the asymptotic behavior of the approximate control for a class of parabolic equations with periodic rapidly oscillating coefficients in composites
The mathematical theory of homogenization studies the asymptotic behavior of problems with small parameters describing for example,heterogeneities(oscillati
We investigate the exact traveling wave solutions of the fifth-order Kaup-Kuperschmidt equation.The bifurcation and exact solutions of a general first-order
