CPT Student Seminar: Lovelock-AdS gravity: vacuum degeneracy and conserved charges
In this talk we will derive an expression for conserved charges in Lovelock antiâ€“de Sitter gravity for solutions having k-fold degenerate vacua, making manifest a link between the degeneracy of a given vacuum and the nonlinearity of the energy formula. The level of degeneracy fixes the relevant order in the curvature where the mass of a black hole solution is contained. As a matter of fact, the full charge can be consistently truncated and expressed in terms of powers of the Weyl tensor. This may be interpreted as a natural generalization of the Ashtekar-Magnon-Das formula for any Lovelock-AdS gravity theories.
