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.
