摘要
本文首先说明简约PF—环与零可换PF—环是一致的 ,接着证明环R是简经PF—环当且仅当对于R的任一元r,如果x∈lR(r) ,则存在 y∈lR(r)使得x =xy =yx ,利用这一内刻划 ,获知正规几乎PP—环是简约PF—环 ,并获得简约PF—环的一些性质 .
This article first states the consistency between reduce PF ring and zero PF ring,then proves that if x∈l R(r),then y∈l R(r),thus x=xy=yx,through which weve got to know that normal almost PP ring is reduce PF ring and some of the properties of reduce PF ring are justified.
