摘要
In this paper, we study the a posteriori error estimate for weak Galerkin finite element method solving elliptic problems. A residual type error estimator is proposed and is proven to be reliable and efficient. This estimator provides global upper and lower bounds on the exact error in a discrete H-1-norm. Numerical experiments are given to illustrate the effectiveness of the proposed error estimator.
