Superconvergence and Gradient Recovery of Linear Finite Elements for the LaplaceBeltrami Operator on General Surfaces

Superconvergence and Gradient Recovery of Linear Finite Elements for the LaplaceBeltrami Operator on General Surfaces: "Huayi Wei, Long Chen, and Yunqing Huang

Superconvergence results and several gradient recovery methods of finite element methods in flat spaces are generalized to the surface linear finite element method for the LaplaceBeltrami equation on general surfaces with mildly structured triangular meshes. For a large class of practically useful ... [SIAM J. Numer. Anal. 48, 1920 (2010)] published Thu Nov 11, 2010."
