Type-B analogues of some combinatorial objects related to noncrossing
George Washington University
refreshments at 3:45pm
Two interesting combinatorial objects having enumerative connections with
(type-A) noncrossing partitions are the associahedron and permutations with
certain pattern restrictions. We will describe type-B analogues of these
objects, and several results relating them to type-B noncrossing
partitions. We will discuss further properties which parallel those known
for type A.
