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 $D_{F,G}(s)$ of Siegel modular forms $F$ and $G$ of degree two, which was introduced by Kohnen and the second author, is computed numer…
