Seshadri constants in finite subgroups of abelian surfaces

Luis Fuentes Garcia

Published 2006-04-17Version 1

Given an etale quotient q:X->Y of smooth projective varieties we relate the simple Seshadri constant of a line bundle M on Y with the multiple Seshadri constant of q*M in the points of the fiber. We apply this method to compute the Seshadri constant of polarized abelian surfaces in the points of a finite subgroup.
