β¦ Synopsis
The goal of this work is to develop a functorial transfer of properties between a module $A$ and the category ${\mathcal M}{E}$ of right modules over its endomorphism ring, $E$, that is more sensitive than the traditional starting point, $\textnormal{Hom}(A, \cdot )$. The main result is a factorization $\textnormal{q}{A}\textnormal{t}{A}$ of the left adjoint $\textnormal{T}{A}$ of $\textnormal{Hom}(A, \cdot )$, where $\textnormal{t}{A}$ is a category equivalence and $\textnormal{ q}{A}$ is a forgetful functor. Applications include a characterization of the finitely generated submodules of the right $E$-modules $\textnormal{Hom}(A,G)$, a connection between quasi-projective modules and flat modules, an extension of some recent work on endomorphism rings of $\Sigma$-quasi-projective modules, an extension of Fuller's Theorem, characterizations of several self-generating properties and injective properties, and a connection between $\Sigma$-self-generators and quasi-projective modules.

This book is intended to provide a self-contained account of much of the theory of rings and modules. The theme of the text throughout is the relationship between the one-sided ideal structure a ring may possess and the behavior of its categories of modules. Following a brief outline of the foundati
