The singularities of $A_g^P$

Algebraic Geometry 2016-04-21 v1

Abstract

We complete the proof given earlier by one of us that the singularities of the perfect cone compactification AgPA_g^P of the coarse moduli space AgA_g of principally polarized abelian gg-folds are terminal if g6g\ge 6, and canonical if g=5g=5.
