研究了具有自反条件的环自同态,拓展了自反环的概念,引入α-rf环,讨论其与相关环的关系.证明了若R是半素的α-rf环,则R x (x^n)是α-rf环,其中(xn)〉是由xn生成的理想;对于右Ore环R和环R的自同构a,若R是α-rf环,则R的经典右商环Q(R)是α-rf环.推广了Kwak和Lcc的一些研究结果.
This note studies rings endomorphisms with the reflexive condition. The notion of a-rt rings, a genera|izatin of reflexive rings,is introduced,the relations between α-rf rings and related rings are discussed. It is proved that if R is a semiprime a-rf ring,then R[x]/(xn) is an a-rf ring,where (xn) is the ideal generated by xn;For a right Ore ring R with Q its classical right quotient ring and an automorphism a of a ring R, if R is a-rf ring, then Q is also α-rf ring. As consequences, some conclusions of Kwak-Lee were generalized.
