产品动作中圈积产品的闭合

The closures of wreath products in product action

I. Ponomarenko, A. V. Vasil'ev

摘要:

设$m$是正整数,$Ω$是有限集。$G\le$ Sym $(Ω)$的$m$-闭包是$Ω$上最大的置换群,在其对笛卡尔积$Ω^m$的诱导作用中具有与$G$相同的轨道.给出了乘积作用下圈积的$m$-闭包的精确公式。作为推论,得到了这个$m$-闭包包含在因子的$m$-闭包的圈积中的一个充分条件.

英文摘要:

Let $m$ be a positive integer and let $Ω$ be a finite set. The $m$-closure of $G\le$Sym$(Ω)$ is the largest permutation group on $Ω$ having the same orbits as $G$ in its induced action on the Cartesian product $Ω^m$. The exact formula for the $m$-closure of the wreath product in product action is given. As a corollary, a sufficient condition is obtained for this $m$-closure to be included in the wreath product of the $m$-closures of the factors.
