Large Order Enumerative Geometry, Black Holes and Black Rings
Sergei Alexandrov, Albrecht Klemm, Boris Pioline
Exploiting newly available data on Gopakumar-Vafa invariants at high genus for one-parameter hypergeometric Calabi-Yau threefolds, we study numerically the growth of the 5D indices…

Mock modularity of Calabi-Yau threefolds
Sergei Alexandrov, Khalil Bendriss
Generating functions of D4-D2-D0 BPS indices, appearing in Calabi-Yau compactifications of type IIA string theory and identical to rank 0 Donaldson-Thomas invariants, are…

Resurgence of Refined Topological Strings and Dual Partition Functions
Sergey Alexandrov, Marcos Mariño, Boris Pioline
We study the resurgent structure of the refined topological string partition function on a non-compact Calabi-Yau threefold, at large orders in the string coupling constant a…
