“Solution phase space and conserved charges
associated with exact symmetries”
Abstract: In this talk, I will present a general formulation for calculating conserved charges associated
with exact symmetries in the context of covariant gravitational theories. The method is based on
``covariant phase space method". Introducing the notion of ``solution phase space", which is the phase
space built by family of solutions parametrized by some parameters, one can calculate the mass, angular
momentum, and electric charge etc, in a single formulation, for general family of solutions (including
black holes), in any dimension, and with any asymptotics. Moreover, the codimension-2 surfaces of
integration are almost relaxed to be chosen arbitrarily. At the end, I will apply the formulation to find
conserved charges and first law(s) of thermodynamics for the Kerr-dS black holes, unifying them with the
Kerr and Kerr-AdS black holes.
