Abstract

We study the weak finite element method solving convection-diffusion equations. A weak finite element scheme is presented based on a spacial variational form. We established a weak embedding inequality that is very useful in the weak finite element analysis. The optimal order error estimates are derived in the discrete H1H^1-norm, the L2L_2-norm and the LL_\infty-norm, respectively. In particular, the H1H^1-superconvergence of order k+2k+2 is given under certain condition. Finally, numerical examples are provided to illustrate our theoretical analysis
