A Two-grid Method for Coupled Free Flow with Porous Media Flow
This paper presents a two-grid method for solving systems of partial differential equations modelling free flow coupled with porous media flow. This work considers both the coupled Stokes and Darcy as well as the coupled ...
On the Coupling of Finite Volume and Discontinuous Galerkin Method for Elliptic Problems
The coupling of cell-centered finite volume method with primal discontinuous Galerkin method is introduced in this paper for elliptic problems. Convergence of the method with respect to the mesh size is proved. Numerical ...
On the Constants in Inverse Inequalities in L2
In this paper we determine the constants in multivariate Markov inequalities in the L2-norm on an interval, a triangle and a tetrahedron. Using orthonormal polynomials, we derive explicit expression for the constants on ...
