SUMMARY:Localization of the action in AdS/CFT - Pietro Genolini (DAMTP)
DTSTART:20190502T120000Z

DESCRIPTION:I will derive a simple formula for the action of any supersymm
 etric solution to minimal gauged supergravity in the context of the AdS_4/
 CFT_3 correspondence. Such solutions are equipped with a supersymmetric Ki
 lling vector\, and I will show that the holographically renormalized actio
 n may be expressed entirely in terms of the weights of this vector field a
 t its fixed points\, together with certain topological data. In this sense
 \, the classical gravitational partition function localizes in the bulk\, 
 and depends only on the topology of the fixed point set.
