Dual Garside Structure of Braids and Free Cumulants of Products
Séminaire lotharingien de combinatoire, Tome 72 (2014-2015)
We count the n-strand braids whose normal decomposition has length at most 2 in the dual braid monoid~Bn+* by reducing the question to a computation of free cumulants for a product of independent variables, for which we establish a general formula.
