SUMMARY:Workshop / Seminar:Colloquium Seminar: Dynamical algebraic combinatorics and webs
DESCRIPTION:Many combinatorial objects with strikingly good enumerative formulae also have remarkable dynamical behavior and underlying algebraic structure. In this talk\, we consider the promotion action on certain rectangular tableaux and explain its small\, predictable order by reinterpreting promotion as a rotation in disguise. We show how the search for this visual explanation of combinatorial dynamics led to the solution of an algebraic problem involving web bases and a generalization of the six-vertex model of statistical physics. We find that this framework includes several unexpected combinatorial objects of interest: alternating sign matrices\, plane partitions\, and their symmetry classes (joint with Ashleigh Adams). This talk is based primarily on joint work with Christian Gaetz\, Stephan Pfannerer\, Oliver Pechenik\, and Joshua P. Swanson.
