Speaker: Prof. Tony Bahri (Rider University) http://users.rider.edu/~bahri/ Time: Tuesday, June 19, 12(NOON)--1PM Room: Carslaw 707A Lunch: after the talk (at Taste at Sydney Uni, i.e. "Law School Annex Cafe") --------------------------------------------------- Title: New Topological Constructions in Toric Geometry and Topology Abstract: certain natural subspaces of a product of CW complexes, called polyhedral products, play an important role in a variety of different fields including: toric varieties, toric manifolds/orbifolds, intersections of quadrics, homotopy theory, algebraic combinatorics complements of subspace arrangements, robotics and group theory. The talk will survey certain combinatorics based constructions on polyhedral products which allow for a description of the cohomology rings of certain families of toric manifolds in a particularly compact form. The new constructions will be related to a generalization of the basic Davis- Januszkiewicz construction of toric manifolds. This report is based on joint work with Martin Bendersky, Fred Cohen and Sam Gitler. --------------------------------------------------- Web site for Geometry Seminar is at: http://www.maths.usyd.edu.au/u/SemConf/Geometry/index.html
