Description
Kerr-Schild geometry has recently seen a surge of interest, appearing in double-copy constructions, in the highly-regular gauge used in the second-order self-force, and elsewhere. This talk explores some of the remarkable properties of Kerr-Schild geometry: It can be used to eliminate nonlinearities in Einstein's equation, can improve accuracy in perturbation theory, can be used to generate large classes of new solutions to Maxwell's equations, and also to generate new solutions for high-frequency gravitational (and other) waves. These results provide a wealth of new tools which have just begun to be explored.
