On Singletons and Adjacencies of Set Partitions of Type B

William Y. C. Chen, David G. L. Wang

Published 2009-10-22Version 1

We show that the joint distribution of the number of singleton pairs and the number of adjacency pairs is symmetric over the set partitions of type $B_n$ without zero-block, in analogy with the result of Callan for ordinary partitions.
