Title: Toric systems and toric degenerations
Abstract:
Given a full exceptional collection in del Pezzo surface, we may associated a toric surface using so-called toric system. Those toric surfaces share several properties with the original del Pezzo surfaces. More specifically, these toric surfaces seem to be the toric degeneration of the del Pezzo surfaces. In this talk, I will introduce the toric surface construction, based on the work by Hille and Perling. Then we discuss how these toric varieties can be viewed as the toric degeneration of the underlying del Pezzo surfaces.
