PhD defense at the LPTHE library (Paris) on Tuesday, 4th of september, at 2pm

Charles Cosnier Horeau

"Amplitudes BPS et fonctions automorphes en théorie des cordes"

Abstract: I will present the idea of black hole microstate counting in string theory vacua with extended supersymmetry (N=4), and explain how the degeneracy of certain BPS black holes in four dimension can be extracted from exact couplings in the low energy effective action of a three dimensional model. This set of conjectures will be motivated with supersymmetry constraints, non-perturbative symmetries, and agreement with known results from the literature.

How to reach LPTHE
