Higher-Derivative Supergravity, Wrapped M5-branes, and Theories of Class
Nikolay Bobev, Anthony M. Charles, Dongmin Gang +2
We study the interplay between four-derivative 4d gauged supergravity, holography, wrapped M5-branes, and theories of class . Using results from Chern-Simons theory on…
Dyonic black hole degeneracies in string theory from Dabholkar-Harvey degeneracies
Abhishek Chowdhury, Abhiram Kidambi, Sameer Murthy +2
The degeneracies of single-centered dyonic -BPS black holes (BH) in Type II string theory on K3 are known to be coefficients of certain mock Jacobi forms arisi…
One-loop determinants for black holes in 4d gauged supergravity
Kiril Hristov, Ivano Lodato, Valentin Reys
We continue the effort of defining and evaluating the quantum entropy function for supersymmetric black holes in 4d gauged supergravity, initiated in [1803.05920]. T…
BRST quantization and equivariant cohomology: localization with asymptotic boundaries
Bernard de Wit, Sameer Murthy, Valentin Reys
We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields,…
On the quantum entropy function in 4d gauged supergravity
Kiril Hristov, Ivano Lodato, Valentin Reys
We analyze BPS black hole attractors in the conformal 4d gauged supergravity formalism and apply the technique known as supergravity localization in order to evaluate Sen's quantum…
