摘要：
We propose a discontinuous finite volume element (DFVE) method for second order elliptic and parabolic problems. Discontinuous bilinear functions are used as the trial functions. We give the stability analysis of this DFVE method and derive the optimal error estimates in the broken H-1- norm. Specifically, the optimal L-2- error is obtained for the first time for the bilinear DFVE methods solving elliptic and parabolic problems.
