Description: | Commutative Algebra Seminar Speaker: Rajiv Garg Date & Time: 6th February, 11:45am-13:00pm Venue: Room 215 Title: Boij-S\ddot{\text{o}}derberg Theory over Standard Graded Rings Abstract: In 2009, Eisenbud and Schreyer prove that extremal rays of Betti cone over a polynomial ring are spanned by Betti diagrams of pure Cohen-Macaulay S-modules, where S={\sf k}[X_1,\dots, X_n]. In this talk, we discuss Boij-S\ddot{\text{o}}derberg theory for standard graded {\sf k}-algebras. We note the obstacles in using their techniques in the general situation and identify classes of rings where we can prove some of these results. |
