Lowest-degree robust finite element scheme for a fourth-order elliptic singular perturbation problem on rectangular grids
Huilan Zeng, Chen-Song Zhang, Shuo Zhang
In this paper, a piecewise quadratic nonconforming finite element method on rectangular grids for a fourth-order elliptic singular perturbation problem is presented. This proposed…

Lowest-degree piecewise polynomial de Rham complex on general quadrilateral grids
Qimeng Quan, Xia Ji, Shuo Zhang
This paper is devoted to the construction of finite elements on grids that consist of general quadrilaterals not limited in parallelograms. Two finite elements defined as Ciarlet's…
