Location:  3866 East Hall (4:00 PM to 5:00 PM)

Title:  All roads lead to the associahedron!

Abstract:   You many know that in ancient times all roads lead to Rome. In combinatorics it seems that all roads lead to the associahedron! Working through a small example, we will see that the following combinatorial structures give rise to an associahedron: triangulations of the n-gon, binary trees, associativity rules, catalan numbers, frieze patterns, pseudolines arrangements, cluster algebras, and toric varieties. In this talk, time permitting, I will show how all of these concepts relate to our humble polytope. No specific background is required, I will use one motivating example to bring the audience on a tour de force though combinatorics.
