Algebraic Geometry Date:  Wednesday, March 13, 2013 Location:  3088 East Hall (4:00 PM to 6:00 PM) Title:  Syzygies via Lie algebra cohomology Abstract:   I will explain the isomorphism between the space of syzygies of arbitrary projective quadratic embeddings and certain Lie algebra cohomology. The isomorphism is based on Koszul duality theory. As an illustration we calculate syzygies of the Plucker embedding of the Grassmannian of 2-dimensional planes. Talk is based on a joint work with A.Gorodentsev, A.Rudakov math.arxiv:0602316 Speaker:  Anton Khoroshkin Institution:  Stonybrook Event Organizer:        Edit this event (login required).
