Abstract

In this note, we prove the inductive blockwise Alperin weight condition for PSU(4,3) by establishing an equivariant bijection between 2-irreducible Brauer characters and 2-weights of the 2-cover of PSU(4,3) and for PSU(6,2) by establishing an equivariant bijection between 3-irreducible Brauer characters and 3-weights of the 3-cover of PSU(6,2). Thus the inductive blockwise Alperin weight condition holds for the simple groups PSU(n,q) with n7 for every prime dividing its order, since the other cases are treated.

PSU(4, 3) 和 PSU(6, 2) 的归纳块状 Alperin 权重条件

摘要

在这篇笔记中,我们证明了归纳块状 Alperin 权重条件 电源(4,3) 通过在 2-不可约布劳尔特征和 2-权重之间建立等变双射 2'-的封面 电源(4,3) 并且对于 电源(6,2) 通过在 3-不可约布劳尔特征和 3-权重之间建立等变双射 3'-的封面 电源(6,2). 因此,归纳块状 Alperin 权重条件适用于简单群 电源(n,q)n7 对于每个素数除以它的顺序,因为其他情况被处理。
