摘要

在本文中，我们研究了罗米克（Funct Anal Appl 39(2):52-155, 2005）独立提出的一种置换统计量。这个统计量统计的是罗宾逊-申斯泰德程序在应用于给定排列时发生的碰撞次数。我们对凹凸统计量做了几种解释，其中包括表格形状，也包括关于排列和递增子序列的极值问题。我们从结构和枚举的角度研究了凹凸统计量的几个方面。

A Bump Statistic on Permutations Resulting from the Robinson–Schensted Correspondence

In this paper, we investigate a permutation statistic that was independently introduced by Romik (Funct Anal Appl 39(2):52–155, 2005). This statistic counts the number of bumps that occur during the execution of the Robinson–Schensted procedure when applied to a given permutation. We provide several interpretations of this bump statistic that include the tableaux shape and also as an extremal problem concerning permutations and increasing subsequences. Several aspects of this bump statistic are investigated from both structural and enumerative viewpoints.
