BASIC PRERADICALS AND MAIN INJECTIVE MODULES

Raggi, F; Ríos, J; Rincon, H; Fernandez-Alonso, R (2009)

We consider those injective modules that determine every left exact preradical and we call them main injective modules. We construct a main injective module for every ring and we prove some of its properties. In particular ...
The lattice structure of preradicals

Raggi, F; Montes, JR; Rincon, H; Fernandez-Alonso, R; Signoret, C (2002)

In this paper we study the lattice of all preradicals on a ring R. We describe this lattice, we prove that it is an atomic and coatomic lattice and we describe the atoms and coatoms. We also give characterizations of simple ...
