摘要：

We investigate a parabolic problem from the point of view of stability and approximation properties of increasing order mixed (in space) finite element methods. Previous estimates for the Raviart-Thomas projection are proven to be sharp. We analyze the effects of mixed finite element discretization in space to present transient error estimates (for semidiscrete mixed finite element methods). The results in this paper (submitted in Oct. 1993) complement the results already published in [6-8].
