Abstract: The recently discovered connection between quantum Seiberg-Witten curves and differential equations arising from black hole and fuzzball perturbation theory has provided a new set of powerful computational techniques for estimating observables such as quasi-normal modes, tidal deformations, amplification factors, waveforms, and more. The results obtained through this new approach have been tested against several well-established methods in the literature. Moreover, it has been employed to investigate the differences and connections between black holes and regular geometries like fuzzballs.
As a notable example, many results focus on a particular spherically symmetric solution of Einstein’s theory in five dimensions, known as the Topological Star. This solution is regular in certain regions of its parameter space, while also admitting a limit that reproduces the Schwarzschild geometry with an extra compact direction.
