Harmonic Maass forms associated with CM newforms
Stephan Ehlen, Yingkun Li, Markus Schwagenscheidt
In this paper, we use a regularized theta lifting to construct harmonic Maass forms corresponding to binary theta functions of weight under the -operator. As a result,…
CM values of higher automorphic Green functions for orthogonal groups
Jan Hendrik Bruinier, Stephan Ehlen, Tonghai Yang
Gross and Zagier conjectured that the CM values (of certain Hecke translates) of the automorphic Green function for the elliptic modular group at positive integral s…
On the modular completion of certain generating functions
Kathrin Bringmann, Stephan Ehlen, Markus Schwagenscheidt
We complete several generating functions to non-holomorphic modular forms in two variables. For instance, we consider the generating function of a natural family of meromorphic mod…
Central -values of elliptic curves and local polynomials
Stephan Ehlen, Pavel Guerzhoy, Ben Kane +1
Here we study the recently introduced notion of a locally harmonic Maass form and its applications to the theory of -functions. In particular, we find finite formulas for certai…
Computing Invariants of the Weil representation
Stephan Ehlen, Nils-Peter Skoruppa
We propose an algorithm for computing bases and dimensions of spaces of invariants of Weil representations of associated to finite quadratic modules. We…
CM values of regularized theta lifts and harmonic weak Maaß forms of weight one
Stephan Ehlen
We study special values of regularized theta lifts at complex multiplication (CM) points. In particular, we show that CM values of Borcherds products can be expressed in terms of f…
