论文摘要
我们将小学Abelian $ p $ - 组的非平地分机按$ psl_2(q)$进行分类,其中奇数$ p $ divining $ q-1 $,用于不可减少的诱导措施,计算相关的低维共同体学组,并描述此类扩展的自构术组。
We classify the nonsplit extensions of elementary abelian $p$-groups by $PSL_2(q)$, with odd $p$ dividing $q-1$, for an irreducible induced action, calculate the relevant low-dimensional cohomology groups, and describe the automorphism groups of such extensions.
