Abstract
In this project, we will explore advanced aspects of black hole physics and their perturbations using the isomonodromic method. Our initial focus will be to investigate superradiant instability and the behavior of frequencies for massive scalar perturbations in the Kerr-Newman black hole as it approaches extremality, employing the Riemann-Hilbert map for the confluent Heun equation and as…
