Equivariant Localization in Supergravity

25.02.2026 11:00 – 12:00

Supersymmetric solutions to supergravity theories continue to play a key role in many aspects of string/M-theory. We will explain how important BPS quantities, including central charges, black hole entropy and the on-shell action, can be computed for supersymmetric solutions of supergravity without ever solving the equations of motion. Instead one exploits the fact that the solutions have a Killing vector and a set of equivariantly closed differential forms. This allows one to compute just by inputting some global data and utilising localisation theorems. We explain the formalism and illustrate with some examples.
