The digest
High Level Overview
This lecture outlines a novel interdisciplinary framework bridging string theory—specifically mirror symmetry and topological string theory—with black hole perturbation theory. The core concept is that certain spectral problems arising in black hole perturbations, particularly quasi-normal mode computations central to gravitational wave physics, can be analyzed using advanced mathematical tools developed in string theory and supersymmetric gauge theories. This connection not only opens new avenues for exact analytical results in gravitational physics but also enriches our understanding of quantum geometry and non-perturbative effects. The talk is highly relevant for researchers in theoretical physics, particularly those exploring the interface between quantum gravity, string theory, and gravitational wave astrophysics.
