Algebra Seminar

Title: Syzygies, Igusa's pictures and identities among relations
Speaker: Professor Jean-Louis Loday
Speaker Info: CNRS, Strasbourg, France and MSRI
Brief Description:
Special Note: Joint Algebra/Topology Seminar !

Given a group presented by generators and relations one would like to construct a cellular model of its classifying space, and also a resolution of the trivial module {\bf Z}. Up to dimension 2 the solution of both problems is classical. We show how the next step is related to Igusa's pictures (certain planar graphs labelled by the presentation) and to identities among relations.
