Quasinormal modes of charged black holes with corrections from nonlinear electrodynamics

We study quasinormal modes related to gravitational and electromagnetic perturbations of spherically symmetric charged black holes in nonlinear electrodynamics. Beyond the linear Maxwell electrodynamics, we consider a class Lagrangian with higher-order corrections written by field strength its Hodge dual arbitrary coefficients, parametrize for frequencies terms coefficients. It is confirmed that isospectrality under parity generally violated due As applications, Euler-Heisenberg Born-Infeld electrodynamics are calculated, then it clarified effects act lengthen oscillation period enhance damping rate modes.
