Annular noncrossing permutations and minimal transitive factorizations

Combinatorics 2022-03-22 v2

Abstract

We give two combinatorial proofs of Goulden and Jackson's formula for the number of minimal transitive factorizations of a permutation when the permutation has two cycles. We use the recent result of Goulden, Nica, and Oancea on the number of maximal chains of annular noncrossing partitions of type BB.
