Derivatives of -series of weakly holomorphic cusp forms
Nikolaos Diamantis, Fredrik Strömberg
Based on the theory of -series associated with weakly holomorphic modular forms in \cite{DLRR}, we derive explicit formulas for central values of derivatives of -series as in…

Computation of harmonic weak Maass forms
Jan H. Bruinier, Fredrik Strömberg
Harmonic weak Maass forms of half-integral weight are the subject of many recent works. They are closely related to Ramanujan's mock theta functions, their theta lifts give rise to…

Numerical Computation of a Certain Dirichlet Series Attached to Siegel Modular Forms of Degree Two
Nathan Ryan, Nils-Peter Skoruppa, Fredrik Stroemberg
The Rankin convolution type Dirichlet series of Siegel modular forms and of degree two, which was introduced by Kohnen and the second author, is computed numer…
