Speaker: Pasha Galashin (Cornell) Title: Amplituhedra and origami Abstract: I will outline the combinatorial machinery behind a recent proof of the BCFW triangulation conjecture for the amplituhedron. I will mostly focus on the combinatorics of the dimer model on bipartite graphs embedded in a disk, including Kenyon--Smirnov primitives, origami crease patterns, and two punctured versions of planar bipartite graphs related by a surprising combinatorial duality.
