IGAP Mathematical Physics Seminar 02/03

[Christian]

Dear everyone,

We are happy to announce the beginning of an IGAP Mathematical Physics 
webinar series for this semester.

The opening webinar will take place on *Tuesday March 2nd at 14:30*:

Speaker: Nikolay Bobev (Leuven)

Title: The Unreasonable Effectiveness of Higher-Derivative Supergravity 
in AdS_4 Holography

Abstract:

I will describe the four-derivative corrections to four-dimensional N=2 
minimal gauged supergravity and show that they are controlled by two 
constants. Interestingly, the solutions of the equations of motion in 
the two-derivative theory are not modified by the higher-derivative 
corrections. I will use this to arrive at a general formula for the 
regularized on-shell action for any asymptotically locally 
AdS_4 solution of the theory and show how the higher-derivative 
corrections affect black hole thermodynamic quantities in a universal 
way. I will employ these results in the context of holography to derive 
new explicit results for the subleading corrections in the large N 
expansion of supersymmetric partition functions on various compact 
manifolds for a large class of three-dimensional SCFTs arising from M2- 
and M5-branes. I will also briefly discuss possible extensions and 
generalizations of these results.

The meeting will be on Zoom at the following coordinates:
