置换群的基与可表示的布尔 simplicial 复形

Bases of Permutation Groups and Boolean Representable Simplicial Complexes

Stuart Margolis, John Rhodes

AI总结:

本文研究了置换群的基与可表示的布尔 simplicial 复形,提出了不可约列表的定义,并通过猜想为Feit-Thompson定理提供新证明。

摘要:

置换群(X,G)的基是X的一个子集B,其点wise稳定化子是平凡群。一个(X的元素列表(x1,x2,...,xk)是不可约的,如果每个元素不在其前驱的点wise稳定化子中。我们定义了一个可表示的布尔 simplicial 复形B(X,G),使得X的子集Y独立当且仅当其元素的某种排列是不可约的。此外,Y是基当且仅当其闭包是X。我们给出了一些例子,并以一个猜想结束,该猜想的解决将导致Feit-Thompson定理的新证明。

英文摘要:

A base of a permutation group (X,G) is a subset B of X such that its pointwise stabilizer is the trivial group. A list (x1,x2, ... ,xk) of elements of X is irredundant if each element is not in the pointwise stabilizer of its predecessors. We define a Boolean representable simplicial complex B(X,G) such that a subset Y of X is independent if and only if some enumeration of its elements is irredundant. In addition Y is a base if and only if its closure is X. We give a number of examples and close with a conjecture whose solution leads to a new proof of the Feit-Thompson Theorem.
