*讲座内容简介：In the beginning of this talk, I will review the virtual element methods(VEM) for the Poisson and Stokes problems. One can understand the construction of the VEM approach from it. Then, I will present a computable and residual-type a posteriori error estimator of the virtual element method for the Stokes problem. The estimator is proved to be efficient and reliable through two estimates between the estimator and the approximated error. Several numerical examples are shown to verify the efficiency of our estimator when it is combined with the suitable mesh refinement strategy.
