β¦ Synopsis
The lattice of noncrossing set partitions is known to admit an R-labeling. Under this labeling, maximal chains give rise to permutations.
We discuss structural and enumerative properties of the lattice of noncrossing partitions, which pertain to a new permutation statistic, m(a), defined as the number of maximal chains labeled by 0. Miibius inversion results and related facts about the lattice of unrestricted set partitions are also presented.

Let 2 [n] denote the Boolean lattice of order n, that is, the poset of subsets of {1, ..., n} ordered by inclusion. Recall that 2 [n] may be partitioned into what we call the canonical symmetric chain decomposition (due to de Bruijn, Tengbergen, and Kruyswijk), or CSCD. Motivated by a question of FΓΌ
Let 2 [n] be the poset of all subsets of a set with n elements ordered by inclusion. A long chain in this poset is a chain of n&1 subsets starting with a subset with one element and ending with a subset with n&1 elements. In this paper we prove: Given any collection of at most n&2 skipless chains in
Consider the poset 6 n of partitions of an n-element set, ordered by refinement. The sizes of the various ranks within this poset are the Stirling numbers of the second kind. Let a= 1 2 &e log(2)Γ4. We prove the following upper bound for the ratio of the size of the largest antichain to the size of
A partial ordering is defined for monotone projections on a lattice, such that the set of these mappings is a lattice which is isomorphic to a sublattice of the partition lattice.
