从戴克路径到标准杨场景

From Dyck paths to standard Young tableaux

Juan B. Gil, Peter R. W. McNamara, Jordan O. Tirrell, Michael D. Weiner

摘要:

我们提出了9个双射类之间的Dyck路径和类的标准杨tableaux(SYT)。特别是,我们认为SYT的标志和矩形形状,我们给代克路径描述某些SYT的高度最多为3,我们引入了一个特殊的类标记的代克路径的半长度$n$,这是在双射与集合的所有SYT与$n$框。此外,我们提出了双射从某些类的Motzkin路径SYT。作为我们的一些双射的自然框架,我们引入一类集合划分,在某种意义上它与已知的非交叉划分类是对偶的。

英文摘要:

We present nine bijections between classes of Dyck paths and classes of standard Young tableaux (SYT). In particular, we consider SYT of flag and rectangular shapes, we give Dyck path descriptions for certain SYT of height at most 3, and we introduce a special class of labeled Dyck paths of semilength $n$ that is shown to be in bijection with the set of all SYT with $n$ boxes. In addition, we present bijections from certain classes of Motzkin paths to SYT. As a natural framework for some of our bijections, we introduce a class of set partitions which in some sense is dual to the known class of noncrossing partitions.
