These patterns are the solutions (KP solitons) of the Kadomtsev-Petviashvili (KP) equation which describes nonlinear wave interactions of the shallow water waves. Those tools include some decorated Young diagrams and permutations which provide an interesting parametrization of certain cell decomposition of the totally nonnegative Grassmannians.

Title: KP solitons and the Grassmannians

Speaker: Yuji Kodama

Abstract: I will explain how the combinatorics can provide useful tools to classify 2-dimensional patterns of nonlinear waves.

These patterns are the solutions (KP solitons) of the Kadomtsev-Petviashvili (KP) equation which describes nonlinear wave interactions of the shallow water waves. Those tools include some decorated Young diagrams and permutations which provide an interesting parametrization of certain cell decomposition of the totally nonnegative Grassmannians.
