Discrete Geometry and Combinatorics Seminar
Spring 2009
Mondays 2:30 PM to 3:30 in Malott 230
Note new time and room


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.
