Shellability of noncrossing partition lattices
by
Christos A. Athanasiadis

Coauthors: Thomas Brady and Colum Watt

We give a case-free proof that the lattice of noncrossing partitions associated to any finite real reflection group is EL-shellable. Shellability of these lattices was open for the groups of type Dn and those of exceptional type and rank at least three.
