A Multigrid Shifted-Inverse Iteration Algorithm for Periodic Boundary Eigenvalue Problems and its Convergence Analysis

Cai Zhou, Xu Xu & Yuxiang Gao · Asian Journal of Research in Computer Science · 2026

This paper systematically investigates a multigrid finite element method and its convergence theory for a class of second-order Laplace eigenvalue problems subject to periodic boundary conditions. We establish the variational formulation of the eigenvalue problem in periodic Sobo...
