Hodge-Elliptic genera, K3 surfaces and Enumerative Geometry
Michele Cirafici
K3 surfaces play a prominent role in string theory and algebraic geometry. The properties of their enumerative invariants have important consequences in black hole physics and in n…

Indefinite theta functions for counting attractor backgrounds
Gabriel Lopes Cardoso, Michele Cirafici, Suresh Nampuri
In this note, we employ indefinite theta functions to regularize canonical partition functions for single-center dyonic BPS black holes. These partition functions count dyonic dege…
