Spectral Indicator Method for a Non-selfadjoint Steklov Eigenvalue Problem [PDF]
Journal of Scientific Computing, 2018 We propose an efficient numerical method for a non-selfadjoint Steklov eigenvalue problem. The Lagrange finite element is used for discretization and the convergence is proved using the spectral perturbation theory for compact operators.
