Number Theory 2020-04-23 v2

Abstract

In this paper, we give a formula for the extended Gross-Keating datum of a quadratic form defined over a finite extension of Zp\mathbb{Z}_p (for p>2p>2) or a finite unramified extension of Z2\mathbb{Z}_2. As an application, we describe an explicit formula for the Siegel series for Zp\mathbb{Z}_p. We also present the details of algorithms implemented in a Mathematica package to compute the extended Gross-Keating datum and the Siegel series.
