[phys4phys] Strings, Holography & Chaos Seminar April 1 12:00 CEST (IPB, 2nd floor theory seminar room): Vasil Dimitrov

[Mihailo Čubrović]

Dear friends,

On April 1 (Wednesday) at 12:00 CEST we will have a seminar by Vasil 
Dimitrov, in the theory seminar room (Institute of Physics Belgrade, 2nd 
floor). Vasil will be around for three days (Wed-Fri), so if you want to 
have a chat drop me an email and I'll get you in touch. Title and 
abstract follow.

Patch-wise equivariant localization in 5d gauged supergravity

Vasil Dimitrov (Institute for Nuclear Research, Bulgarian Academy of 
Sciences, Sofia)

I will discuss a novel approach for obtaining the Euclidean on-shell 
action of a large class of known (and still to be found) solutions of 5d 
gauged supergravity. The geometries in question include multi-center 
solutions: black holes, black rings, black lenses, topological 
solitons... In the ungauged limit the results match known on-shell 
actions of explicit flat space multi-center geometries. I will discuss 
the localization procedure including the subtleties concerning 
holographic renormalization and dealing with the non-trivial topology of 
the gauge fields due to Chern-Simons terms in 5d.
