A Convergent Nonconforming Adaptive Finite Element Method with Quasi-Optimal Complexity: "Roland Becker, Shipeng Mao, and Zhongci Shi

In this paper, we prove convergence and quasi-optimal complexity of a simple adaptive nonconforming finite element method. In each step of the algorithm, the iterative solution of the discrete system is controlled by an adaptive stopping criterion, and the local refinement is based on either a simp ... [SIAM J. Numer.
