Young置换类

Young classes of permutations

Michael Albert

摘要:

我们把那些具有这样性质的排列类归为一类:对于每一个画面形状,要么该形状的每一个排列都属于该类,要么该形状的任何排列都不属于该类。的特征是在分区(及其共轭)的优势顺序,并表明,对于任何这样的类有一个常数k,这样,在类中没有置换可以包含一个增加和减少的长度为k的序列。

英文摘要:

We characterise those classes of permutations having the property that for every tableau shape either every permutation of that shape or no permutation of that shape belongs to the class. The characterisation is in terms of the dominance order for partitions (and their conjugates) and shows that for any such class there is a constant k such that no permutation in the class can contain both an increasing and a decreasing sequence of length k.
