Bilkent Üniversitesi ODTÜ-Bilkent Cebirsel Geometri SeminerleriJets schemes and toric embedded resolution of rational triple points Meral Tosun One of the aims of J.Nash in an article on the arcs spaces (1968) was to understand resolutions of singularities via the arcs living on the singular variety. He conjectured that there is a one-to-one relation between a family of the irreducible components of the jet schemes of an hypersurface centered at the singular point and the essential divisors on every resolution. J.Fernandez de Bobadilla and M.Pe Pereira (2011) have shown his conjecture, but the proof is not constructive to get the resolution from the arc space. We will construct an embedded toric resolution of singularities of type rtp from the irreducible components of the jet schemes. NOT: One day before the seminar, an announcement with the Zoom meeting 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 ags 02.12.2022 |
