Error Estimates of Triangular Mixed Finite Element Methods for Distributed Parameter Systems

摘要：

This goal of this paper is to study a priori error estimates of triangular mixed. nite element methods for distributed parameter systems. The state and the co-state are discretized by the lowest order Raviart-Thomas mixed finite element spaces and the control is discretized by piecewise constant functions. We derive a priori error estimates for the coupled state and control approximation. Finally, we present an numerical example which con.rm our theoretical results.
