According to the a posteriori error estimator,a bubble placement method and constrained BLMG strategy are applied to solve elliptic problem with discontinuo
In this manuscript we present a simple and efficient approximation for some class of Fourier multiplier operators Tm on the Paley-Wiener spaces Hh,using the
This paper deals with discontinuous finite volume approximations of the distributed optimal control problems governed by a class of semilinear parabolic par
The approximation of an electromagnetic wave propagating through a highly oscillatory medium is challenging.Using standard edge finite elements a very fine
In this article,we have discussed a domain decomposition method with non-matching grids(known as mortar method)for solving second order elliptic problems us
The variable space grid method based on finite-differences is applied to the one-dimensional Stefan problem with time-dependent boundary conditions describi
In this paper,we develop a numerical technique for the solution of fifth order singularly perturbed boundary value problems using exponential quartic spline
