Description:
Commutative algebra seminar Speaker: Sara Faridi, Dalhousie University Day: Saturday, 17th February. Time: 04:00 - 05:00 p.m., Venue: Ramanujan Hall Title: Monomial Ideals with Linear Resolution This talk is about various generalizations that have been made of the concept of a chordal graph to hypergraphs and simplicial complexes, with a view toward generalizing a theorem of Froeberg in 1990 which characterized ideals generated by degree 2 monomials with linear resolution in terms of chordal graphs. Some of the higher dimensional counterparts of chordal graphs are constructed from a topological point of view, and some from a purely combinatorial one. We will discuss older and newer work in this area, based partly on joint work with Emma Connon and recent work with Mina Bigdeli.
