A note on multiple Seshadri constants on surfaces
Luis Fuentes Garcia
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. I…

Cyclic coverings and Seshadri constants on smooth surfaces
Luis Fuentes Garcia
We study the Seshadri constants of cyclic coverings of smooth surfaces. The existence of an automorphism on these surfaces can be used to produce Seshadri exceptional curves. We gi…
