Cornell Discrete Geometry and Combinatorics Seminar
Fall 2015
Mondays 2:30-3:30 pm 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, graph theory, and combinatorial Hopf algebras.

This semester the seminar is run jointly by Marcelo Aguiar and Karola Mészáros. Please feel free to suggest speakers or volunteer to speak.

Our Founding Fathers are Lou Billera and Bob Connelly.
