AdS black hole symmetries and enstrophy

Using Noether's theorem and the AdS/CFT duality, one may relate the symmetries of the event horizon of an AdS black hole in 3+1 dimensions to conserved charges of the dual conformal fluid in 2+1 dimensions. In this seminar I will speak of a spesific subset of such symmetries called supertranslations, which relate to the approximate conservation of a fluid charge called enstrophy.
