在本文中,G是一个有限群,k是一个特征为p的代数闭域。所有模都取为有限生成的右模,如果U是一个kg -模,则Z (U)表示它的组成长度,Z (U)表示它的集,Q (U)表示它的Frattini子模。我们的目的是研究以下情况:假设。B是具有4阶循环缺陷群D的kg块。D,-是p阶D的唯一子群,H= No (D,-,), C= Co (D,-,)。
Throughout this paper G is a finite group with k an algebraically closed field of characteristic p. Also all modules are to be taken as finitely generated right modules and if U is a KG-module, Z (U) will denote its composition length, Z (U) its socle and Q (U) its Frattini submodule. We aim to study the following situation:HYPOTHESIS. B is a KG-block with cyclic defect group D of order 4= pd. D,-, is the unique subgroup of D of order p, H= No (D,-,) and C= Co (D,-,).
