We consider the approximation of elliptic eigenvalue problem with an immersed interface.The main aim of this paper is to prove the stability and convergence
Superconvergence and a posteriori error estimators of recovery type are analyzed for the 4-node hybrid stress quadrilateral finite element method proposed b
We present a simple method at material interface to remove numerical oscillations when the finite-difference time domain(FDTD)method is used to solve Maxwel
First we construct a conforming rectangular element and a conforming cubic element only with the degrees of freedom on an element 8+2 and 18+3 for stress an
We present a HDG method for linear elasticity on general polyhedral meshes,based on a strong symmetric stress formulation.The key feature of this method is
The design of mixed finite element methods in linear elasticity with symmetric stress approximations has been a longstanding open problem.In this talk,we pr
