Abstract:Let $ p\ge 5$ be a prime and let $ G$ be a finite group. We prove that $ G$ is $ p$-solvable of $ p$-length at most $ 2$ if there are at most two distinct $ p'$-character degrees in the principal $ p$-block of $ G$. This generalizes a theorem of Isaacs-Smith as well as a recent result of three of the present authors.

主块中具有with'字符度数少的组

摘要:让我们$ p \ ge 5 $成为素数,让我们$ G $成为有限群。如果在的主块中最多存在两个不同的字符度,我们证明最大$ G $$ p $$ p $长度。这概括了艾萨克斯-史密斯定理,以及三个作者的最新结果。$ 2 $$ p'$$ p $$ G $
