Positional Marked Patterns in Permutations

Sittipong Thamrongpairoj, Jeffrey B. Remmel

We define and study positional marked patterns, permutations $τ$ where one of elements in $τ$ is underlined. Given a permutation $σ$ , we say that $σ$ has a $τ$ -match at position $i…

Classical pattern distributions in $S_{n} (132)$ and $S_{n} (123)$

Dun Qiu, Jeffrey Remmel

Classical pattern avoidance and occurrence are well studied in the symmetric group $S_{n}$ . In this paper, we provide explicit recurrence relations to the generating func…

Counting Consecutive Pattern Matches in $S_{n} (132)$ and $S_{n} (123)$

Ran Pan, Dun Qiu, Jeffrey Remmel

In this paper, we study the distribution of consecutive patterns in the set of 123-avoiding permutations and the set of 132-avoiding permutations, that is, in $S_{n} (123)$ …

Schur Function Expansions and the Rational Shuffle Theorem

Dun Qiu, Jeffrey Remmel

Gorsky and Negut introduced operators $Q_{m, n}$ on symmetric functions and conjectured that, in the case where $m$ and $n$ are relatively prime, the expression $Q_{m, n} (1)$ is gi…

Patterns in words of ordered set partitions

Dun Qiu, Jeffrey Remmel

An ordered set partition of ${1, 2, \dots, n}$ is a partition with an ordering on the parts. Let $O P_{n, k}$ be the set of ordered set partitions of $[n]$ with $k$ blocks.…

A note on passing from a quasi-symmetric function expansion to a Schur function expansion of a symmetric function

Adriano Garsia, Jeffrey Remmel

Egge, Loehr and Warrington gave in \cite{ELW} a combinatorial formula that permits to convert the expansion of a symmetric function, homogeneous of degree $n$ , in terms of Gessel's…
