Maximum-norm Error Estimates of Mixed Finite Element Methods for Bilinear Elliptic Optimal Control Problems
摘要
Abstract
Mixed finite element approximation of a bilinear elliptic optimal control problem is considered.The state and co-state are approximated by the lowest order Raviart-Thomas mixed finite element and the control variable is approximated by piecewise constant functions.Maximum-norm error estimates both for the control variable,the state variables and the co-state variables are derived.关键词
