摘要

我们研究了有限简单群的码度同构问题。特别是，我们证明了这样一个群是由其不可还原字符的编码度（计算多重性）决定的。证明对所有简单群都是统一的，只取决于通过阿尔丁-蒂茨的简单阶定理进行的分类。

The codegree isomorphism problem for finite simple groups

We study the codegree isomorphism problem for finite simple groups. In particular, we show that such a group is determined by the codegrees (counting multiplicity) of its irreducible characters. The proof is uniform for all simple groups and only depends on the classification by means of Artin–Tits’ simple order theorem.
