Abstract

In this paper we review and discuss several aspects of supertranslations and their associated algebras at the horizon of a Schwarzschild black hole. We will compare two different approaches on horizon supertranslations, which were recently considered in separate publications. Furthermore we describe a possible holographic description of a Schwarzschild black hole in terms of a large N boundary theory, which accommodates the Goldstone bosons of the horizon supertranslations. This paper contains a review and a discussion of several aspects of supertranslations and their associated algebras at the horizon of a Schwarzschild black hole. Two different approaches on horizon supertranslations recently considered in separate publications are compared. A possible holographic description of a Schwarzschild black hole in terms of a large N boundary theory is discussed, which accommodates the Goldstone bosons of the horizon supertranslations.
