| 摘 要： | 本文从右陪集分解的角度建立扩张理论。从一个已知的扩张出发,得到A之一组自同构及因子团。又A之一组自同构及因子团已给时,确存在A被B的一个相应扩张。再又A之一组自同构及因子团的两个扩张除等价外是唯一地决定。

| Abstract: | This article attempts to establish the extension theory from right accompany set decomposition to discuss the following problems-
Based on a known extension,an automorphism for A and factor group are obtained. It exists that A is extended correspondingly by B when an automorphism for A and factor group are obtained. It is absolutely determined for the two extensions in the automorphism and factor group ,if they are not e-qual. |
