Iterated integrals for generalized Appell functions
Aradhita Chattopadhyaya, Jan Manschot
Appell functions are a large class of multi-variable quasi-elliptic functions, which are also instances of higher depth mock modular forms. A central aspect of these functions is t…
Remarks on Vafa-Witten theory, or how to sit on a wall
Sergei Alexandrov, Aradhita Chattopadhyaya
We prove three results about refined VW invariants on Hirzebruch surfaces. First, we crucially simplify the modular anomaly equation satisfied by the generating series of t…
Appell Functions for General Lattices
Aradhita Chattopadhyaya, Jan Manschot
We study Appell functions associated to an arbitrary positive definite lattice and a choice of linearly independent vectors , . Thes…
Sign of BPS index for dyons
Aradhita Chattopadhyaya
In this paper we argue how the sign changes on an average for the positive weight mock modular forms associated with the type II string black holes compactified on orb…
Numerical experiments on coefficients of instanton partition functions
Aradhita Chattopadhyaya, Jan Manschot
We analyze the coefficients of partition functions of Vafa-Witten theory for the complex projective plane . We experimentally study the growth of the coefficients fo…
Scaling Black Holes and Modularity
Aradhita Chattopadhyaya, Jan Manschot, Swapnamay Mondal
Scaling black holes are solutions of supergravity with multiple black hole singularities, which can be adiabatically connected to a single center black hole solution. We develop te…
