报告题目：Convergence analysis of adaptive finite element methods for optimal control problems with integral constraint
报告摘要：As one of the most important method to boost the accurcy of finite element discretization, adaptive finite element methods have been used successfully for scientific and engineering computations. In this talk, we study an adaptive finite element method of optimal control problems with integral control constraint. The convergence is proved by a contraction between two consecutive loops. Additionally, we find that the adaptive finite element method can achieve the best convergence rate. Some examples are provided to validate the theoretical analysis.
