On a Divisor Modular Form and a Theta Lift

Andreas Mono, Larry Rolen, Johann Stumpenhusen

In 1975, Zagier introduced the highly influential hyperbolic Poincaré series . We connect the divisor modular form of to a new weak Maass form . Furth…

A modular framework for generalized Hurwitz class numbers III

Andreas Mono

In , Pei and Wang introduced higher level analogs of the classical Cohen--Eisenstein series. In recent joint work with Beckwith, we found a weight sesquiharmoni…

Flipping operators and locally harmonic Maass forms

Kathrin Bringmann, Andreas Mono, Larry Rolen

In the theory of integral weight harmonic Maass forms of manageable growth, two key differential operators, the Bol operator and the shadow operator, play a fundamental role. Harmo…

A modular framework for generalized Hurwitz class numbers II

Olivia Beckwith, Andreas Mono

In a recent preprint, we constructed a sesquiharmonic Maass form of weight and level with odd and squarefree. Extending seminal work by Duke, I…

A modular framework for generalized Hurwitz class numbers I

Olivia Beckwith, Andreas Mono

We discover a non-trivial relation between the mock modular generating functions of the level and level Hurwitz class numbers. This relation yields a holomorphic modular fo…

Central -values of newforms and local polynomials

Joshua Males, Andreas Mono, Larry Rolen +1

In this paper, we characterize the vanishing of twisted central -values attached to newforms of square-free level in terms of certain polynomials of quadratic forms introduced b…

Linear congruence relations for exponents of Borcherds products

Andreas Mono, Badri Vishal Pandey

For all positive powers of primes , we prove the existence of infinitely many linear congruences between the exponents of twisted Borcherds products arising from a suitabl…

A modular framework for functions of Knopp and indefinite binary quadratic forms

Kathrin Bringmann, Andreas Mono

We study functions introduced by Knopp and complete them to non-holomorphic bimodular forms of positive integral weight related to indefinite binary quadratic forms. We investigate…

Local Maaß forms and Eichler--Selberg type relations for negative weight vector-valued mock modular forms

Joshua Males, Andreas Mono

By comparing two different evaluations of a modified (à la Borcherds) higher Siegel theta lift on even lattices of signature , we prove Eichler--Selberg type relations for a…

Locally harmonic Maaß forms of positive even weight

Andreas Mono

We twist Zagier's function by a sign function and a genus character. Assuming weight , and letting be a positive non-square discriminant, we…

Higher depth mock theta functions and -hypergeometric series

Joshua Males, Andreas Mono, Larry Rolen

In the theory of harmonic Maass forms and mock modular forms, mock theta functions are distinguished examples which arose from -hypergeometric examples of Ramanujan. Recently, t…

Eisenstein series of even weight and integral binary quadratic forms

Andreas Mono

We prove a conjecture of Matsusaka on the analytic continuationof hyperbolic Eisenstein series in weight on the full modular group .

Multidimensional small divisor functions

Andreas Mono

This is a short note generalizing the construction from arXiv:1906.07410, arXiv:2009.04955 to multi-indices. We recommend to consider both references first. We obtain polar harmoni…

Polar harmonic Maaß forms and holomorphic projection

Joshua Males, Andreas Mono, Larry Rolen

Recently, Mertens, Ono, and the third author studied mock modular analogues of Eisenstein series. Their coefficients are given by small divisor functions, and have shadows given by…

On a conjecture of Kaneko and Koike

Andreas Mono

In 2006, Kaneko and Koike defined extremal quasimodular forms and proved their existence in depth and . After normalizing and restricting to the case of depth at most , t…
