Title: A variational approach to axially symmetric Maxwell perturbations of Kerr-de Sitter black holes

Abstract: The Kerr-de Sitter black hole family is a solution of Einstein's equations of general relativity with a positive cosmological constant. After reviewing some background on these spacetimes, we shall discuss the proof that there exits a phase space of canonical variables for the (unconstrained) axially symmetric Maxwell's equations propagating on Kerr-de Sitter, such that their motion is restricted to the level sets of a positive-definite Hamiltonian, despite the ergo-region. If time permits, we shall discuss the equivalent results for the corresponding fully coupled (and constrained) Einstein-Maxwell initial value problem.
