关于超幂零根与次幂等根的一个特征

A CHARACTERISTIC ON SUPERNJLPOTENT RADICALS AND SUBIDEMPOTENT RADICALS

本文我们引入了规范根的概念，讨论了它的基本性质，证明了一个遗传根是超幂零根或次幂等恨当且仅当它是规范根，从而给出了超幂零根与次幂零等根的一个统一刻划。

In this paper,we introduce the concept of norm radicals,and prove the following theorem:A hereditary radical is supernilpotent or subidempotent if and only if it is a norm radical.
