Bilkent Üniversitesi ODTÜ-Bilkent Cebirsel Geometri SeminerleriOn some invariants of the tangent cones of numerical semigroup rings Pınar Mete The minimal free resolution is a very useful tool for extracting information about modules. Many important numerical invariants of a module such as Hilbert function and Betti numbers can be deduced from its minimal free resolution. Stamate gave a broad survey on these topics when the modules are the semigroup ring or its tangent cone for a numerical semigroup S. He also stated the problem of describing the Betti numbers and the minimal free resolution for the tangent cone when S is 4-generated semigroup which is symmetric. In this talk, I will first give some of our results, based on a joint work with E.E. Zengin on the problem. Then, I will talk about our ongoing study which is an application 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 15.02.2024 |
