- W1480454399 abstract "It is well known that the Rickart property of rings is not a left-right symmetric property. We extend the notion of the left Rickart property of rings to a general module theoretic setting and define π-Rickart modules. We study this notion for a right R-module M R where R is any ring and obtain its basic properties. While it is known that the endomorphism ring of a Rickart module is a right Rickart ring, we show that the endomorphism ring of an π-Rickart module is not a left Rickart ring in general. If M R is a finitely generated π-Rickart module, we prove that End R (M) is a left Rickart ring. We prove that an π-Rickart module with no set of infinitely many nonzero orthogonal idempotents in its endomorphism ring is a Baer module. π-Rickart modules are shown to satisfy a certain kind of nonsingularity which we term βendo-nonsingularity.β Among other results, we prove that M is endo-nonsingular and End R (M) is a left extending ring iff M is a Baer module and End R (M) is left cononsingular." @default.
