摘要
本文将交换环上有限生成模的单自同态的有关结果推广到PI-环上,得到如下类似结果定理若R是PI-环,则R上任意有限生成模的单自同态是同构。
The motivation for this paper comes from trying to extend the result on endmorphisms of finitely generated modules over commutative rings to PI-rings.In doing so we obtain a similar result. Theorem For a PI ring R .Injective endmorphisms of finitely generated R modusles are isomorphisms if and only if R is primitive.
