Abstract
Let be an abelian surface and let be a finite group of automorphisms of fixing the origin. Assume that the analytic representation of is irreducible. We give a classification of the pairs such that the quotient is smooth. In particular, we prove that with an elliptic curve and that in all cases. Moreover, for fixed , there are only finitely many pairs up to isomorphism. This fills a small gap in the literature and completes the classification of smooth quotients of abelian varieties by finite groups fixing the origin started by the first two authors.
