Dear Topologists and Friends of Topology, This is a reminder that Jeff Mermin is giving the seminar this afternoon at 3:30 in MSCS 514. Title: Simplicial, Cellular, and CW resolutions Abstract: One of the most exciting recent developments in commutative algebra has been the discovery that free resolutions of multigraded objects such as monomial ideals can be encoded using topology. I'll explain what free resolutions are and describe the connection.
