Discrete Geometry and Combinatorics Seminar
Spring 2008
Mondays 4:30 PM to 5:30 in Malott 205
(Note the new day, Monday, and time 4:30 for our meeting.)


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.  To see lists of earlier talks in this series, click here.
