Singularities of regular black holes and the monodromy method for asymptotic quasinormal modes
arXiv:2205.05935 · doi:10.1088/1674-1137/aca07c
Abstract
We use the monodromy method to investigate the asymptotic quasinormal modes of regular black holes based on the explicit Stokes portraits. We find that, for regular black holes with spherical symmetry and a single shape function, the analytical forms of the asymptotic frequency spectrum are not universal and do not depend on the multipole number but on the presence of complex singularities and the trajectory of asymptotic solutions along the Stokes lines.
