Seshadri constants of toric surfaces

Abstract: In this talk, after introducing Seshadri constants of projective surfaces and some known results, I will focus on the case of toric projective surfaces associated to lattice polygons. I will prove some relations between the rationality of Seshadri constants and the geometry of the polygon, and I will present some possible applications to the case of weighted projective planes. This is based on a joint work with Antonio Laface.
