格群的根式类

Radial Classes of L-groups

本文讨论了各种格群根式类之间的关系,并刻画了决定完备根式类、积根式类,子积根式类、完备积根式类、完备子积根式类、完备闭核根式类及极根式类的根式映射。

In this paper the relations between several radical classes of l-groups are discussed,and the radical mappings are characterized which determine complete radical classes,product radical classes, subproduct radical classes,complete product radical classes,complete subproduct radical classes,com- plete closed-kernel radical classes and polar radical classes.
