Title: Snake decomposition of lattice path matroids

Speaker: Jerónimo Valencia Porras  Affiliation: University of Waterloo Location: MC 5501

Abstract: Lattice path matroids (LPMs) are positroids whose base polytopes have a nice decomposition. We provide a geometric perspective to this decomposition in terms of fences and their order polytopes, which correspond to a certain class of LPMs we call snakes.
