Explicit inner product formulas and Bessel period formulas for HST lifts
Explicit inner product formulas and Bessel period formulas for HST lifts
We explicitly give an inner product formula and a Bessel period formula for theta series on GSp(4), which was studied by Harris, Soudry and Taylor. As a consequence, we prove a non-vanishing of the theta series of small weights and we give a criterion for the non-vanishing of the theta …
