Description
In certain regimes, perturbations of black branes are
described by effective theories of fluid and elastic
dynamics. I present recent results on a general account of
the dynamics of black branes in supergravity theories,
including any type of brane bound state. The type of
theories that arise from this analysis are novel types of
forced fluid dynamics living on dynamical hypersurfaces,
which include force terms due to the presence of
Chern-Simons couplings in the supergravity actions. I
highlight the relevance of this work for the existence of
probe brane configurations in arbitrary supergravity
backgrounds with fluxes. Furthermore, I will discuss the
connections between these effective theories and the DBI action.
