Noncrossing Partitions for the Group Dn
Abstract. The poset of noncrossing partitions can be naturally defined for any finite Coxeter group W . It is a self-dual, graded lattice which reduces to the classical lattice of noncrossing partitions of {1, 2, . . . , n} defined by Kreweras in 1972 when W is the symmetric group Sn, and to its type B analogue defined by the second author in 1997 when W is the hyperoctahedral group. We give a ...
متن کاملON k-NONCROSSING PARTITIONS
In this paper we prove a duality between k-noncrossing partitions over [n] = {1, . . . , n} and k-noncrossing braids over [n − 1]. This duality is derived directly via (generalized) vacillating tableaux which are in correspondence to tangled-diagrams [6]. We give a combinatorial interpretation of the bijection in terms of the contraction of arcs of tangled-diagrams. Furthermore it induces by re...
متن کاملOn Trees and Noncrossing Partitions
We give a simple and natural proof of (an extension of) the identity P (k, l, n) = P2(k − 1, l − 1, n − 1). The number P (k, l, n) counts noncrossing partitions of {1, 2, . . . , l} into n parts such that no part contains two numbers x and y, 0 < y − x < k. The lower index 2 indicates partitions with no part of size three or more. We use the identity to give quick proofs of the closed formulae ...
متن کاملOn the Noncrossing Partitions of a Cycle
This article defines the paritions of a finite set structured in a cycle which possesses the property that a pair of points belonging to a class and a pair of points belonging to another class cannot be in a crossed way. It establishes that these partitions form a lattice and it specifies some of the descriptive and enumerative properties of the lattice; it computes in particular the Möbius fun...
متن کاملON 2-REGULAR, k-NONCROSSING PARTITIONS
In this paper we prove a bijection between 2-regular, k-noncrossing partitions and k-noncrossing enhanced partitions. Via this bijection we enumerate 2-regular, 3-noncrossing partitions using an enumeration result [1] for enhanced 3-noncrossing partitions. In addition we derive the asymptotics for the numbers of 2-regular, 3-noncrossing partitions using the BirkhoffTrijtzinky analytic theory of...
