The no-hair theorem states that all black hole solutions of the Einstein-Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three externally observable classical parameters: mass, electric charge, and angular momentum. Malcolm J. Perry's 73 research works with 4,091 citations and 4,385 reads, including: Central charges for AdS black holes These represent an extension of the BMS group that we call the conformal BMS group. These black holes live in an anti-de Sitter spacetime, i.e., a spacetime with negative cosmological constant. Nontrivial diffeomorphisms act on the horizon of a generic 4D black holes and create distinguishing features referred to as soft hair. In this paper we show that if one adds a negative cosmological constant, there is a similar set of .
