On some generalized $q$ -Eulerian polynomials

Zhicong Lin

The $(q, r)$ -Eulerian polynomials are the $(\maj-$$\exc,\fix,\exc)$ enumerative polynomials of permutations. Using Shareshian and Wachs' exponential generating function of these Eul…

A symmetrical q-Eulerian identity

Guoniu Han, Zhicong Lin, Jiang Zeng

We find a $q$ -analog of the following symmetrical identity involving binomial coefficients $(m n)$ and Eulerian numbers $A_{n, m}$ , due to Chung, Graham and Knuth [{\it J. Co…

Jacobi-Stirling polynomials and $P$ -partitions

Ira M. Gessel, Zhicong Lin, Jiang Zeng

We investigate the diagonal generating function of the Jacobi-Stirling numbers of the second kind $ \JS(n+k,n;z)$ by generalizing the analogous results for the Stirling and Legendr…
