Weak discrete maximum principle of isoparametric finite element methods in curvilinear polyhedra
Buyang Li, Weifeng Qiu, Yupei Xie +1
The weak maximum principle of the isoparametric finite element method is proved for the Poisson equation under the Dirichlet boundary condition in a (possibly concave) curvilinear…

A note on the Monge-Ampère type equations with general source terms
Weifeng Qiu, Lan Tang
In this paper we consider the generalised solutions to the Monge-Amp{è}re type equations with general source terms. We firstly prove the so-called comparison principle and then giv…
