置换类的圈积

Wreath Products of Permutation Classes

Robert Brignall

摘要:

一个在模式参与下封闭的置换类可以用它的基来描述。两个置换类X和Y的圈积构造X \wr Y也是闭的,并且我们研究了具有如下性质的类Y:对于任何基于环的类X,圈积X \wr Y也是基于环的.

英文摘要:

A permutation class which is closed under pattern involvement may be described in terms of its basis. The wreath product construction X \wr Y of two permutation classes X and Y is also closed, and we investigate classes Y with the property that, for any finitely based class X, the wreath product X \wr Y is also finitely based.
