Abstract

Some conditions for the Galois map to be injective are given in the groupoid acting on a noncommutative ring context. In the particular case in which the Galois extension is a central Galois algebra, it is given a complete characterization of that kind of extension with Galois map bijective.

在Galois地图上进行类动作

摘要

Galois映射为内射的一些条件在作用于非交换环上下文的群中给出。在Galois扩展是中心Galois代数的特定情况下，可以使用Galois映射双射图对这种扩展进行完整的刻画。
