Marking Algorithms in Permutation Tableaux and Transformations on Linked Partitions
Carol Jian Wang, Meryl Nan Wang · Preprints.org · 2025
In this paper, we focus on the internal structural characteristics of permutation tableaux and their correspondence with linked partitions. We begin by introducing new statistics or permutation tableaux, designed to thoroughly describe various positional relationships among the topmost 1’s and the rightmost restricted 0’s. Subsequently, we develop two marking algorithms for permutation tableaux, each from the perspective of columns and rows. Additionally, we introduce tugging and rebound transformations, which elucidate the generative relationship from original partitions to linked partitions. As a result,we demonstrate that the construction of these two marking algorithms in permutation tableaux provides a straightforward method for enumerating the crossing number and nesting number of the corresponding linked partitions.
