Vanishing properties of Fourier coefficients of holomorphic -quotients
Kathrin Bringmann, Guoniu Han, Bernhard Heim +1
In this paper, we study vanishing of Fourier coefficients of holomorphic -quotients. We investigate examples of two different types: the first one involves integral weight CM ne…
Sign changes of Fourier coefficients for holomorphic eta-quotients
Kathrin Bringmann, Guoniu Han, Bernhard Heim +1
In this paper we study sign changes of an infinite class of -quotients which are holomorphic modular forms. There is also a relation to Hurwitz class numbers.
Periodic sign changes for weakly holomorphic -quotients
Kathrin Bringmann, Guoniu Han, Bernhard Heim +1
In this paper, we study sign changes of weakly holomorphic modular forms which are given as -quotients. We give representative examples for forms of negative weight, weight zero…
On a sign-change conjecture of Schlosser and Zhou
Kathrin Bringmann, Bernhard Heim, Ben Kane
In this paper, we investigate the signs changes of Fourier coefficients of infinite products of -series of Rogers--Ramanujan type. In particular, we prove a conjecture made by S…
Asymptotics of commuting -tuples in symmetric groups and log-concavity
Kathrin Bringmann, Johann Franke, Bernhard Heim
Denote by the number of -tuples of elements in the symmetric group with commuting components, normalized by the order of . In this paper, we prove as…
