The research of nonlinear degenerate wave equations and its application on high accurarcy analysis

Author(s): Zhiyan Li, Linghui Liu, Chunguang Zhao, Shutao Jiang

The convergence analysis of the bilinear finite element method to a class of non-linear degenerate wave equation on anisotropic meshes is considered in this paper. Moreover, the global superconvergence for semidiscrete scheme is proposed through interpolation instead of the Ritz Volterra projection of the exact solution.
