Explicit congruences for mock modular forms [PDF]

open access: yes, 2015
In recent work of Bringmann, Guerzhoy, and the first author, p-adic modular forms were constructed from mock modular forms.

ZAGIER DUALITY FOR HARMONIC WEAK MAASS FORMS OF INTEGRAL WEIGHT [PDF]

open access: yes, 2010
We show the existence of "Zagier duality" between vector valued harmonic weak Maass forms and vector valued weakly holomorphic modular forms of integral weight.

Locally harmonic Maass forms and the kernel of the Shintani lift [PDF]

open access: yes, 2014
In this paper we define a new type of modular object and construct explicit examples of such functions. Our functions are closely related to cusp forms constructed by Zagier which played an important role in the construction by Kohnen and Zagier of a ...

$p$-adic properties of coefficients of weakly holomorphic modular forms [PDF]

open access: yes, 2009
We examine the Fourier coefficients of modular forms in a canonical basis for the spaces of weakly holomorphic modular forms of weights 4, 6, 8, 10, and 14, and show that these coefficients are often highly divisible by the primes 2, 3, and 5.Comment: 16

Topological Strings and (Almost) Modular Forms [PDF]

open access: yes, 2006
The B-model topological string theory on a Calabi-Yau threefold X has a symmetry group Gamma, generated by monodromies of the periods of X. This acts on the topological string wave function in a natural way, governed by the quantum mechanics of the phase

Polar harmonic Maass forms and their applications [PDF]

open access: yes, 2016
In this survey, we present recent results of the authors about non-meromorphic modular objects known as polar harmonic Maass forms. These include the computation of Fourier coefficients of meromorphic modular forms and relations between inner products of

Heterotic-string amplitudes at one loop: modular graph forms and relations to open strings [PDF]

open access: yes, 2019
We investigate one-loop four-point scattering of non-abelian gauge bosons in heterotic string theory and identify new connections with the corresponding open-string amplitude.

Petersson inner products of weight-one modular forms [PDF]

open access: yesJournal für die Reine und Angewandte Mathematik, 2012
In this paper we study the regularized Petersson product between a holomorphic theta series associated to a positive definite binary quadratic form and a weakly holomorphic weight-one modular form with integral Fourier coefficients.

Algebraic formulas for the coefficients of mock theta functions and Weyl vectors of Borcherds products [PDF]

open access: yes, 2017
We present some applications of the Kudla-Millson and the Millson theta lift. The two lifts map weakly holomorphic modular functions to vector valued harmonic Maass forms of weight $3/2$ and $1/2$, respectively.

Higher depth quantum modular forms, multiple Eichler integrals, and $$\mathfrak {sl}_3$$sl3 false theta functions [PDF]

open access: yesResearch in the Mathematical Sciences, 2017
We introduce and study higher depth quantum modular forms. We construct two families of examples coming from rank two false theta functions, whose “companions” in the lower half-plane can be also realized both as double Eichler integrals and as non ...
