Speaker: Prof. Gil Kalai, Hebrew Univ. of Jerusalem & Yale University
Location: 1003 Giedt
Start time: Mon, Oct 7 2013, 5:10PM

I will describe some old and new problems in combinatorics and geometry. I) Geometric questions around Borsuk's problem. II) Questions that involve combinatorics and topology. Solving puzzles based on triangulations of spheres, Embedding of 2-dimensional complexes in four-dimensional space. III) Questions about convex polytopes. IV) Questions around Tverberg theorem. V) A question about random graphs. This talk is suitable for undergraduate students.
