A high order stabilization-free virtual element method for general second-order elliptic eigenvalue problem
Liangkun Xu, Shixi Wang, Yidu Yang +1
In this paper, we discuss a novel higher-order stabilization-free virtual element method for general second-order elliptic eigenvalue problems. Optimal a priori error estimates are…

Adaptive FEM with optimal convergence rate for non-self-adjoint eigenvalue problems
Shixi Wang, Hai Bi, Yidu Yang
In this paper, we first discuss the optimal convergence of the adaptive finite element methods for non-self-adjoint eigenvalue problems. We present new theoretical error estimators…
