Orta Doğu Teknik Üniversitesi ODTÜ-Bilkent Cebirsel Geometri SeminerleriComputation of automorphism groups of Enriques surfaces Ichiro Shimada By Torelli's theorem for K3 surfaces, the automorphism group of a complex Enriques surface is determined by the Hodge structure of the covering K3 surface. However, in many cases, explicit computations are very heavy and practically infeasible. We give a method by which one can compute a finitely generated set of automorphism groups of various Enriques surfaces and their nef cones. This is a joint work with Simon Brandhorst. NOT: One day before the seminar, an announcement with the Zoom link will be sent to those who registered with Sertöz. If you have registered before for one of the previous talks, there is no need to register again; you will automatically receive a link for this talk too. If you have not registered before, please contact him at sertoz@bilkent.edu.tr. Cebirsel Geometri İngilizce Zoom admin 13.12.2021 |
