Cuspidal components of Siegel modular forms for large discrete series representations of ${\mathrm{Sp}}_4(\mathbb{R})$

Shuji Horinaga, Hiro-aki Narita

In this paper, we consider automorphic forms on ${\mathrm{Sp}}_4({\mathbb{A}}_{\mathbb{Q}})$ which generate large discrete series representations of ${\mathrm{Sp}}_4(\mathbb{R})$ as $(\mat…
