Hurwitz class number relations and mock modular forms

Kathrin Bringmann, Jia-Wei Guo, Ben Kane +2

A classical class number relation of Hurwitz expresses the Fourier coefficients of the product of a unary theta function and the class number generating function. Here, we establis…

On -congruences for meromorphic modular forms with supersingularity

Kathrin Bringmann, Pavel Guerzhoy, Ben Kane +2

In this paper, we investigate congruences for meromorphic modular forms which have a pole at a single point in the fundamental domain of . For a p…

On Kleinian mock modular forms

Claudia Alfes-Neumann, Michael Mertens

We give an explicit and computationally efficient construction of harmonic weak Maass forms which map to weight newforms under the -operator. Our work uses a new non-analyti…

Hecke eigenforms for meromorphic cusp forms

Kathrin Bringmann, Ben Kane, Michael H. Mertens

In this paper, we construct Hecke eigenforms for two families of quotient spaces of meromorphic cusp forms on . We show that each quotient space in the f…

On Jacobi--Weierstrass mock modular forms

Claudia Alfes-Neumann, Jens Funke, Michael Mertens +1

We construct harmonic weak Maass forms that map to cusp forms of weight with rational coefficients under the -operator. This generalizes work of the first author, Grif…

Proof of the elliptic expansion Moonshine Conjecture of Căldăraru, He, and Huang

Letong Hong, Michael H. Mertens, Ken Ono +1

Using predictions in mirror symmetry, Căldăraru, He, and Huang recently formulated a "Moonshine Conjecture at Landau-Ginzburg points" for Klein's modular -function at and…

On Weierstrass mock modular forms and a dimension formula for certain vertex operator algebras

Lea Beneish, Michael H. Mertens

Using techniques from the theory of mock modular forms and harmonic Maass forms, especially Weierstrass mock modular forms, we establish several dimension formulas for certain stro…

Mock modular Eisenstein series with Nebentypus

Michael H. Mertens, Ken Ono, Larry Rolen

By the theory of Eisenstein series, generating functions of various divisor functions arise as modular forms. It is natural to ask whether further divisor functions arise systemati…

Periodicities for Taylor coefficients of half-integral weight modular forms

Pavel Guerzhoy, Michael H. Mertens, Larry Rolen

Congruences of Fourier coefficients of modular forms have long been an object of central study. By comparison, the arithmetic of other expansions of modular forms, in particular Ta…

Modular forms of virtually real-arithmetic type I -- Mixed mock modular forms yield vector-valued modular forms

Michael H. Mertens, Martin Raum

The theory of elliptic modular forms has gained significant momentum from the discovery of relaxed yet well-behaved notions of modularity, such as mock modular forms, higher order…

O'Nan moonshine and arithmetic

John F. R. Duncan, Michael H. Mertens, Ken Ono

Answering a question posed by Conway and Norton in their seminal 1979 paper on moonshine, we prove the existence of a graded infinite-dimensional module for the sporadic simple gro…

A proof of the Thompson Moonshine Conjecture

Michael J. Griffin, Michael H. Mertens

In this paper we prove the existence of an infinite dimensional graded super-module for the finite sporadic Thompson group whose McKay-Thompson series are weakly holomorphic m…

On the number of parts of integer partitions lying in given residue classes

Olivia Beckwith, Michael Mertens

Improving upon previous work on the subject, we use Wright's Circle Method to derive an asymptotic formula for the number of parts in all partitions of an integer that are in any g…

The Number of Parts in Certain Residue Classes of Integer Partitions

Olivia Beckwith, Michael Mertens

We use the Circle Method to derive asymptotic formulas for functions related to the number of parts of partitions in particular residue classes.

Lacunary recurrences for Eisenstein series

Michael H. Mertens, Larry Rolen

Using results from the theory of modular forms, we reprove and extend a result of Romik about lacunary recurrence relations for Eisenstein series.

On class invariants for non-holomorphic modular functions and a question of Bruinier and Ono

Michael H. Mertens, Larry Rolen

Recently, Bruinier and Ono found an algebraic formula for the partition function in terms of traces of singular moduli of a certain non-holomorphic modular function. In this paper…

-adic properties of modular shifted convolution Dirichlet series

Kathrin Bringmann, Michael H. Mertens, Ken Ono

Hoffstein and Hulse recently introduced the notion of shifted convolution Dirichlet series for pairs of modular forms and . The second two authors investigated certain s…

Asymptotic formulae for partition ranks

Jehanne Dousse, Michael H. Mertens

Using an extension of Wright's version of the circle method, we obtain asymptotic formulae for partition ranks similar to formulae for partition cranks which where conjectured by F…

Special values of shifted convolution Dirichlet series

Michael H. Mertens, Ken Ono

In a recent important paper, Hoffstein and Hulse generalized the notion of Rankin-Selberg convolution -functions by defining shifted convolution -functions. We investigate sy…
