A simple low-degree optimal finite element scheme for the elastic transmission eigenvalue problem
Yingxia Xi, Xia Ji, Shuo Zhang
The paper presents a finite element scheme for the elastic transmission eigenvalue problem written as a fourth order eigenvalue problem. The scheme uses piecewise cubic polynomials…

A high accuracy nonconforming finite element scheme for Helmholtz transmission eigenvalue problem
Yingxia Xi, Xia Ji, Shuo Zhang
In this paper, we consider a cubic nonconforming finite element scheme which does not correspond to a locally defined finite element with Ciarlets triple but ad…
