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…
Statistics on permutations with bounded drop size
Joanna Na Chen, Robin Dapao Zhou
Permutations with bounded drop size, which we also call bounded permutations, was introduced by Chung, Claesson, Dukes and Graham. Petersen introduced a new Mahonian statistic the…
A new decomposition of ascent sequences and Euler--Stirling statistics
Shishuo Fu, Emma Yu Jin, Zhicong Lin +2
As shown by Bousquet-Mélou--Claesson--Dukes--Kitaev (2010), ascent sequences can be used to encode -free posets. It is known that ascent sequences are enumerated by the…
Equidistributed statistics on Fishburn matrices and permutations
Dandan Chen, Sherry H. F. Yan, Robin D. P. Zhou
Recently, Jelínek conjectured that there exists a bijection between certain restricted permutations and Fishburn matrices such that the bijection verifies the equidistribution of s…
Refined Enumeration of Corners in Tree-like Tableaux
Sherry H. F. Yan, Robin D. P. Zhou
Tree-like tableaux are certain fillings of Ferrers diagrams originally introduced by Aval et al., which are in simple bijections with permutation tableaux coming from Postnikov's s…
