Springer Tracts in Advanced Roboticshe notions of Baer, quasi-Baer, and Rickart modules are introduced and studied. Similar to the fact that every Baer ring is nonsingular, we shall see that every Baer module satisfies a weaker notion of nonsingularity of modules (.-nonsingularity) which depends on the endomorphism ring of the module.

A structure theorem for a quasi-Baer ring with a complete set of triangulating idempotents is shown using complete triangular matrix representations. A number of well known results follow as consequen

The chapter begins with the development of necessary and sufficient conditions on a ring so that its maximal right ring of quotients can be decomposed into a direct products of indecomposable rings or into a direct products of prime rings. This relies on results on the idempotent closure clas

The first four chapters of the book discuss rings and modules which generalize injectivity (e.g.,
