Adaptive refinement for eigenvalue problems based on an associated source problem
Stefano Giani, Jeffrey Ovall, Gabriel Pinochet-Soto
We introduce an adaptive finite element scheme for the efficient approximation of a (large) collection of eigenpairs of selfadjoint elliptic operators in which the adaptive refinem…

A Canonical Gauge for Computing of Eigenpairs of the Magnetic Schrödinger Operator
Jeffrey S. Ovall, Li Zhu
We consider the eigenvalue problem for the magnetic Schrödinger operator and take advantage of a property called gauge invariance to transform the given problem into an equivalent…
