In this paper,local a priori,local a posteriori and global a posteriori error estimates are obtained for TQC9 element for the biharmonic equation.An adaptive al
In this paper, we study variational discretization for the constrained optimal control problem goveed by convection dominated diffusion equations, where the sta
We consider the numerical solution of the free boundary Beoulli problem by employing level set formulations.Using a perturbation technique,we derive a second or
In this paper, a discontinuous finite element method for the positive and symmetric, first-order hyperbolic systems (steady and nonsteady state) is constructed
The restrictively preconditioned conjugate gradient (RPCG) method is further developed to solve large sparse system of linear equations of a block two-by-two st
