Bilkent Üniversitesi ODTÜ-Bilkent Cebirsel Geometri SeminerleriApery table, microinvariants and the regularity index Sefa Feza Arslan In this talk, I will first explain the concepts of Apery table of a numerical semigroup introduced by Cortedellas and Zarzuela (Tangent cones of numerical semigroup rings. Contemp. Math. 502, 45–58 (2009)) and the microinvariants of a local ring introduced by Juan Elias (On the deep structure of the blowing-up of curve singularities. Math. Proc. Camb. Philos. Soc. 131, 227–240 (2001)). We use these concepts to give some partial results about a conjecture on the regularity index of a local ring and to give some open problems. 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 21.12.2020 |
