Free cyclic submodules in the context of the projective line

Rings and Algebras 2015-03-18 v1

Abstract

We discuss the free cyclic submodules over an associative ring RR with unity. Special attention is paid to those, which are generated by outliers. This paper describes all orbits of such submodules in the ring of lower triangular 33x33 matrices over a field FF under the action of the general linear group. Besides rings with outliers generating free cyclic submodules, there are also rings with outliers generating only torsion cyclic submodules and without any outliers. We give examples of all cases.
