A note on multiple Seshadri constants on surfaces
Luis Fuentes Garcia
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) is maximal when rL2 is a square.
