In this paper we extend several results known for reduced rings to reduced modules. We prove that for a semiprime module or a module with zero Jacobson radical, the concepts of reduced, symmetric, ps-Armendariz and ZI modules coincide. New examples of reduced modules are furnished: flat modules over reduced rings and modules with zero Jacobson radical ...

Rings decomposed into direct sums of nil rings and certain reduced rings
2016Let R be a ring, E the set of idempotents of R, and N the set of nilpotents. For \(x\in R\), denote by r(x) the right annihilator of x; call x a right p.p. element if there exists \(e\in E\) such that \(xe=x\) and \(r(x)=r(e)\). Let P be the set of all right p.p. elements, and call R a generalized right p.p.
