Noncommutative del Pezzo surfaces
Kazushi Ueda (Univ of Tokyo, Japan)
Abstract: It is known after the works of Artin-Tate-Van den Bergh and Bondal-Polishchuk that noncommutative deformations of the projective plane are classified by triples consisting of a cubic curve and two line bundles. Similarly, Van den Bergh gave a classification of noncommutative quadric surfaces in terms of quadruples consisting of (a degeneration of) an elliptic curve and three line bundles. In the talk, I will discuss a joint work in progress with Tarig Abdelgadir and Shinnosuke Okawa on classifications of noncommutative del Pezzo surfaces.
