A note on multiple Seshadri constants on surfaces

Algebraic Geometry 2007-05-23 v1

Abstract

We give a bound for the multiple Seshadri constants on surfaces with Picard number 1. The result is a natural extension of the bound of A. Steffens for simple Seshadri constants. In particular, we prove that the Seshadri constant ϵ(L;r)\epsilon(L; r) is maximal when rL2rL^2 is a square.
