У оквиру Семинара о струнама, холографији и хаосу, у среду, 1. априла 2026. године у 12 часова у сали 360 Института за физику у Београду, Васил Димитров (Институт за нуклеарна истраживања, Бугарска академија наука) одржаће предавање:
Patch-wise equivariant localization in 5d gauged supergravity
САЖЕТАК:
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.
