关于(p^3-p)/2阶单群的Frobenius结果

Frobenius' result on simple groups of order (p^3-p)/2

Paul Monsky

摘要:

具有相同阶的非同构有限单群对的完整列表是众所周知的。特别地,当p>3时,PSL_2(Z/p)是“唯一的”阶为(p^3-p)/2的单群。不太为人所知的是弗罗贝纽斯在1902年证明了这个唯一性结果。本说明提出了一个版本的弗罗贝纽斯的论点,可能会使用在一个本科生荣誉代数课程。它还包括一个简短的现代证明,针对相同的观众,更早的结果,PSL_2(Z/p)是简单的p>3;一个结果,伽罗瓦在1832年。

英文摘要:

The complete list of pairs of non-isomorphic finite simple groups having the same order is well-known. In particular for p>3, PSL_2(Z/p) is the "only" simple group of order (p^3-p)/2. It's less well-known that Frobenius proved this uniqueness result in 1902. This note presents a version of Frobenius' argument that might be used in an undergraduate honors algebra course. It also includes a short modern proof, aimed at the same audience, of the much earlier result that PSL_2(Z/p) is simple for p>3; a result stated by Galois in 1832.
