Siegel modular forms associated to Weil representations: ${\mathrm{SL}}_2(\mathbb{R})\&{\mathrm{GL}}_2(\mathbb{R})$ cases

Chun-Hui Wang

We investigate explicit modular forms of weights $1/2$ and $3/2$-classical, minus, and fermionic theta series-arising from the classical Weil representation associated to $\operato…
