Imai considered the twisted Koecher-Maass series for Siegel cusp forms of degree 2, twisted by Maass cusp forms and Eisenstein series, and used them to prove the converse theorem for Siegel modular forms. They do not have Euler products, and it is not even known whether they converge absolutely for Re(s)>1. Hence the standard convexity arguments do not apply to give bounds. In this paper, we obtai...... hiện toàn bộ

In the 1960s Igusa determined the graded ring of Siegel modular forms of genus two. He used theta series to construct
