New explicit formulas for Faltings' delta-invariant

Algebraic Geometry 2016-12-06 v3 Number Theory

Abstract

In this paper we give new explicit formulas for Faltings' δ\delta-invariant in terms of integrals of theta functions, and we deduce an explicit lower bound for δ\delta only in terms of the genus and an explicit upper bound for the Arakelov-Green function in terms of δ\delta. Furthermore, we give a canonical extension of δ\delta and the Zhang-Kawazumi invariant φ\varphi to the moduli space of indecomposable principally polarised complex abelian varieties.
