NEP_MiniMax: An approach for NEPs based on minimax approximation of the split coefficient vector

Chenkun Zhang, Jiawei Gu, Lei-Hong Zhang

We propose \textsf{NEP\_MiniMax}, a novel computational method for solving nonlinear eigenvalue problems (NEPs) $T(\lambda )\mathbf{u}=0$ on a Jordan domain $Ω\subset \mathbb{C…
