Changho Han, Trigonal Curves and Associated K3 Surfaces
Changho Han, Trigonal Curves and Associated K3 Surfaces
Speaker Changho Han Korea university K3 surfaces, as a generalization of elliptic curves, have a rich amount of geometric properties. Recalling that elliptic curves are double covers of rational curves branched over 4 distinct points, there are K3 surfaces that are cyclic triple covers of rational surfaces; Artebani and Sarti classified such generic …

Justin Lacini, On Log del Pezzo Surfaces in Positive Characteristic
Justin Lacini, On Log del Pezzo Surfaces in Positive Characteristic
Speaker Justin Lacini Princeton university A log del Pezzo surface is a normal surface with only Kawamata log terminal singularities and anti-ample canonical class. Over the complex numbers, Keel and McKernan have classified all but a bounded family of log del Pezzo surfaces of Picard number one. In this talk we will extend …
