#### Resonance of Plane Partitions

###### Oliver Pechenik (University of Illinois at Urbana-Champaign)

Abstract: A plane partition is a pile of cubes stacked in a corner of a room. We'll discuss the dynamics of an action on plane partitions studied by P. Cameron and D. Fon-der-Flaass (1995). By relating this to a jeu de taquin coming from K-theoretic Schubert calculus, we'll resolve one of their conjectures and obtain new proofs of a number of theorems.
