关于复杂度,亏群与不可分解模的若干说明

摘要

In this paper, we obtain the structures of defect groups of a block B of a p-solvable group with C+G (B)≤2 except for CG+(B)=C-G (B)=2 when p=2. And we also givesome remarks on complexity and indecomposable modules.%在本文中,我们给出了C+G(B)≤2但不满足当p=2时C+G(B)=C-G(B)=2的p-可解群的块B的亏群的结构.同时亦给出关于复杂度与不可分解模的若干说明.
