Localization of eigenvalues for non-self-adjoint Dirac and Klein-Gordon operators
arXiv:2104.13647 · doi:10.1016/j.na.2021.112565
Abstract
This note aims to give prominence to some new results on the absence and localization of eigenvalues for the Dirac and Klein-Gordon operators, starting from known resolvent estimates already established in the literature combined with the renowned Birman-Schwinger principle.
