The false theta functions of Rodgers and their modularity
Abstract In this survey article, we explain how false theta functions can be embedded into a modular framework and show some of the applications of this modularity.

New Expansion Formulas for a Family of the λ‐Generalized Hurwitz‐Lerch Zeta Functions
We derive several new expansion formulas for a new family of the λ‐generalized Hurwitz‐Lerch zeta functions which were introduced by Srivastava (2014). These expansion formulas are obtained by making use of some important fractional calculus theorems such as the generalized Leibniz rules, the Taylor‐like expansions in terms of different functions, and ...

New Relations Involving an Extended Multiparameter Hurwitz‐Lerch Zeta Function with Applications
We derive several new expansion formulas involving an extended multiparameter Hurwitz‐Lerch zeta function introduced and studied recently by Srivastava et al. (2011). These expansions are obtained by using some fractional calculus methods such as the generalized Leibniz rules, the Taylor‐like expansions in terms of different functions, and the ...

Counting Strings, Wound and Bound [PDF]
We analyze zero mode counting problems for Dirac operators that find their origin in string theory backgrounds. A first class of quantum mechanical models for which we compute the number of ground states arises from a string winding an isometric ...

Negative index Jacobi forms and quantum modular forms [PDF]
In this paper, we consider the Fourier coefficients of a special class of meromorphic Jaocbi forms of negative index. Much recent work has been done on such coefficients in the case of Jacobi forms of positive index, but almost nothing is known for ...

A holomorphic anomaly in the elliptic genus [PDF]
We consider a class of gauged linear sigma models (GLSMs) in two dimensions that flow to non-compact (2, 2) superconformal field theories in the infra-red, a prototype of which is the SL(2, R)/U(1) (cigar) coset.

On the Fourier coefficients of negative index meromorphic Jacobi forms [PDF]
In this paper, we consider the Fourier coefficients of meromorphic Jacobi forms of negative index. This extends recent work of Creutzig and the first two authors for the special case of Kac-Wakimoto characters which occur naturally in Lie theory, and ...

A Kronecker-type identity and the representations of a number as a sum of three squares [PDF]
By considering a limiting case of a Kronecker-type identity, we obtain an identity found by both Andrews and Crandall. We then use the Andrews-Crandall identity to give a new proof of a formula of Gauss for the representations of a number as a sum of ...
