Han's conjecture on permutations (Q1362994)

The aim of this paper is to prove the following Theorem 1.1. Let \(\alpha\) and \(\beta\) be circuits on \(\{1,2,\dots, n\}\). If \((\text{exc, den})\alpha= (\text{exc, den})\beta\), then \(\alpha\sim\beta\) (i.e., then one can be obtained from the other by a sequence of Han transpositions).
