Discrete Geometry and Combinatorics Seminar
Fall 2011
Mondays 2:30 PM to 3:30 in Malott 206 

Topics of interest are discrete geometry and algebraic combinatorics, including the geometry and combinatorics of polyhedra, enumeration in partially ordered sets and triangulations, matroid theory, the theory of rigid and flexible frameworks, tilings, packing, and graph theory.

This seminar is run jointly by   Louis Billera (billera@math.cornell.edu), Bob Connelly (connelly@math.cornell.edu) and Ed Swartz (ebs@math.cornell.edu). Please feel free to suggest speakers or volunteer to speak.
