In this paper, we consider a hydrodynamic model of the semiconductor device. The approximate solutions are obtained by a mixed finite volume method for the pote
We study perturbation bound and structured condition number about the minimal nonnegative solution of nonsymmetric algebraic Riccati equation, obtaining a sharp
We propose a quadratically convergent algorithm for computing the invariant subspaces of an Hermitian matrix.Each iteration of the algorithm consists of one mat
A nonoverlapping domain decomposition iterative procedure is developed and analyzed for generalized Stokes problems and their finite element approximate problem
The mortar element method is a new domain decomposition method(DDM) with nonoverlapping subdomains. It can handle the situation where the mesh on different subd
In this article, we analyse three related preconditioned steepest descent algorithms,which are partially popular in Hartree-Fock and Kohn-Sham theory as well as
