Abstract

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 Einstein equations or the Killing spinor equations. Instead one exploits the fact that the solutions have a Killing vector and a set of equivariantly closed forms. This allows one to compute just by inputting some global data and utilising the Berligne-Verne-Atiyah-Bott localisation theorem. We explain the formalism and illustrate with some examples focusing on computing the on-shell action for D=4 and D=5 gauged supergravity theories.
