Rogers' mean value theorem for $S$-arithmetic Siegel transform and applications to the geometry of numbers

Abstract

We prove higher moment formulas for Siegel transforms defined over the space of unimodular $S$-lattices in ${\mathbb{Q}}_S^d$, $d\ge 3$, where in the real case, the formulas are introduced by Rogers (1955). As applications, we obtain the random statements of Gauss circle problem for any convex sets in ${\mathbb{Q}}_S^d$ containing the origin and of the effective Oppenheim conjecture for $S$-arithmetic quadratic forms.
