Proof of a conjecture on the shape-Wilf-equivalence for partially ordered patterns
Lintong Wang, Sherry H. F. Yan
A partially ordered pattern (abbreviated POP) is a partially ordered set (poset) that generalizes the notion of a pattern when we are not concerned with the relative order of some…
Equidistribution of set-valued statistics on standard Young tableaux and transversals
Robin D. P. Zhou, Sherry H. F. Yan
As a natural generalization of permutations, transversals of Young diagrams play an important role in the study of pattern avoiding permutations. Let and $\mathc…
On Refinements of Wilf-Equivalence for Involutions
Sherry H. F. Yan, Lintong Wang, Robin D. P. Zhou
Let (resp. and ) denote the set of permutations (resp. involutions and alternating involutions) of length which avoid t…
Combinatorics of Integer Partitions With Prescribed Perimeter
Zhicong Lin, Huan Xiong, Sherry H. F. Yan
We prove that the number of even parts and the number of times that parts are repeated have the same distribution over integer partitions with a fixed perimeter. This refines Strau…
On a conjecture concerning the shuffle-compatible permutation statistics
Lihong Yang, Sherry H. F. Yan
The notion of shuffle-compatible permutation statistics was implicit in Stanley's work on P-partitions and was first explicitly studied by Gessel and Zhuang. The aim of this paper…
The Gessel Correspondence and the Partial -Positivity of the Eulerian Polynomials on Multiset Stirling Permutations
William Y. C. Chen, Amy M. Fu, Sherry H. F. Yan
Pondering upon the grammatical labeling of 0-1-2 increasing plane trees, we come to the realization that the grammatical labels play a role as records of chopped off leaves of the…
