Title:  Shellability of the uncrossing partial order on matchings

Abstract:

We introduce the uncrossing partial order on matchings, which first arose as the face posets of stratified spaces of planar resistor networks. We discuss its relationship to the type A Bruhat order and give an EC-shelling due to Patricia Hersch and Richard Kenyon.
