Titre |
The unreasonable effectiveness of higher-derivative supergravity in AdS4 holography |
|
Résumé |
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 AdS4 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. |
