On the monotonicity and discrete maximum principle of the finite difference implementation of - finite element method
Hao Li, Xiangxiong Zhang
We show that the fourth order accurate finite difference implementation of continuous finite element method with tensor product of quadratic polynomial basis is monotone thus satis…

Superconvergence of high order finite difference schemes based on variational formulation for elliptic equations
Hao Li, Xiangxiong Zhang
The classical continuous finite element method with Lagrangian basis reduces to a finite difference scheme when all the integrals are replaced by the Gaus…

Superconvergence of - finite element method for elliptic equations with approximated coefficients
Hao Li, Xiangxiong Zhang
We prove that the superconvergence of - finite element method at the Gauss Lobatto quadrature points still holds if variable coefficients in an elliptic problem are repla…
