Analysis of Two-Grid Characteristic Finite Element Methods for Convection-Diffusion Equations
In this paper, two efficient two-grid algorithms for the convection-diffusion problem with a modified characteristic finite element method are studied. We present an optimal error estimate in Lp-norm for the characteristic finite element method unconditionally, while all previous works require certa...
