Nonconforming Quasi-Wilson Finite Element Approximation For The Nonlinear Rosenau Equation |
Abstract | ||
---|---|---|
The nonconforming Quasi-Wilson element is applied to analyze the superconvergence behavior of the fourth-order Rosenau equation by mixed finite element method (FEM). The Crank-Nicolson (CN) fully discrete scheme is developed, and the stability, existence and uniqueness of approximate solution are proved. Further, the superconvergence estimates of order O(h(2)+ tau(2)) for the related variables in the broken H-1-norm are derived. At last, the correctness of theoretical analysis is validated by numerical experiments. Here and later, h and tau are the mesh size and time step, respectively. (C) 2021 Elsevier Ltd.
