The aim of this paper is to increase transparency in the scientific analysis of equity gaps in education. This should be useful in avoiding common ambiguities and misunderstandings in the discourse and in presenting the analyses results in a construc

For $k\ge 1$, the homogeneous symmetric functions $G(k,m)$ of degree $m$ defined by $\sum_{m\ge 0} G(k,m) z^m=\prod_{i\ge 1} \big(1+x_iz+x^2_iz^2+\cdots+x^{k-1}_iz^{k-1}\big)$ are called \emph{Petrie symmetric functions}. As derived by Grinberg and F

We derive some new signed Mahonian polynomials over the complex reflection group $G(r,1,n)=C_r\wr\mathfrak{S}_n$, where the "sign" is taken to be any of the $2r$ $1$-dim characters and the "Mahonian" statistics are the $\mathsf{lmaj}$ defined by Bagn

The genus of a permutation $$\sigma $$ of length n is the nonnegative integer $$g_{\sigma }$$ given by $$n+1-2g_{\sigma }={\textsf {cyc}}(\sigma )+{\textsf {cyc}}(\sigma ^{-1}\zeta _n)$$, where $${\textsf {cyc}}(\sigma )$$ is the number of cycles of

We study the generating function of descent numbers for the permutations with descent pairs of prescribed parities, the distribution of which turns out to be a refinement of median Genocchi numbers. We prove the $\gamma$-positivity for the polynomial

For any integer m ≥ 2 and a set V ⊂ { 1 , … , m } , let ( m , V ) denote the union of congruence classes of the elements in V modulo m . We study the Hankel determinants for the number of Dyck paths with peaks avoiding the heights in the set (

We study the generating polynomial of the flag major index with each one-dimensional character, called signed Mahonian polynomial, over the colored permutation group, the wreath product of a cyclic group with the symmetric group. Using the insertion
