Explicit combinatorial interpretation of Kerov character polynomials as numbers of permutation factorizations
TL;DR: In this paper, an explicit combinatorial interpretation of the coefficients of Kerov character polynomials which express the value of normalized irreducible characters of the symmetric groups S ( n ) in terms of free cumulants R 2, R 3, R 4, R 5, R 6, R 7, R 8 of the Young diagram is given.
Journal ArticleDOI
Asymptotics of characters of symmetric groups related to Stanley character formula
Valentin Féray,Piotr Sniady +1 more
TL;DR: In this article, an upper bound for characters of symmetric groups was shown for Young diagrams with n boxes, r( ) rows and c( ) columns, where r is the minimal number of factors needed to write 2 Sn as a product of transpositions.
Journal ArticleDOI
A simple model of trees for unicellular maps
TL;DR: A recursive bijection is given that explicitly describes the ''recursive part'' of the first bijection, and a very simple description of unicellular maps as pairs made by a plane tree and a permutation-like structure is obtained.
Journal ArticleDOI
The Brownian limit of separable permutations
TL;DR: In this paper, the authors study random uniform permutations in an important class of pattern-avoiding permutations: the separable permutations, and describe the asymptotics of the number of occurrences of any fixed given pattern in such a random permutation in terms of the Brownian excursion.
Journal ArticleDOI
Gaussian fluctuations of Young diagrams and structure constants of Jack characters
Maciej Dołęga,Valentin Féray +1 more
TL;DR: In this paper, the authors considered a deformation of Plancherel measure linked to polynomials and gave the first and second order asymptotics of the bulk of a random Young diagram under this distribution.
