摘要
文章引进FR-环的概念,证明了FR-环的同态像、直积、矩阵环、形式幂级数等都是FR-环,并给出了FR-环与UR-环的关系.
In this paper, the notion of FR-rings is introduced.. It proved that the class of FR-rings is closed under taking homomorphic image, direct product, matrix extension and power series extension. The relationship between the classes of FR-rings and UR-rings is also investigated.
