摘要
研究了任一个超幂零根为零的亚直不可约环所确定的环类 ,证明了由这样的环类所确定的上根都是特殊根 。
In this paper, let σ be an arbitrary suppernilpotent radical, the upper radical detemined by the class of all σ-semisimple subdirectly irreducible rings is studied. We prove that is a special radical and give some characterization conditions of this class radical.
