Résumé |
I will discuss worldvolume effective theories describing black holes and branes in higher-dimensional gravity and supergravity. I will review how these can be used to perturbatively construct non-trivial black holes solutions with various topologies, geometries and with arbitrary asymptotics. Examples include asymptotically flat black helicoidal branes, rings and tori as well as asymptotically plane wave black Scherk-surfaces. I will also briefly discuss extremal horizons and applications to antibrane metastable states in supergravity. Finally, I will show how this effective theory can be used to study instabilities of asymptotically flat black rings as well as (Anti)-de Sitter black rings. |
