Title: ON SIMPLE-DIRECT MODULES
Abstract:
A right module M is called direct-injective (or C2) if every submodule isomorphic to a summand of M is itself a summand. Dually, a module M is called direct-projective (or D2) if for every submodule N of M with M/N isomorphic to summand of M, then N is a summand of M. Recently, in a series of papers “simple” versions of the aforementioned modules have been investigated ([3], [4], [5]). These modules are termed as “simple-direct-injective” and
“simple-direct-projective,” respectively.
In this talk, we shall discuss the structure of these modules over certain rings including the ring of integers. Besides, it will be shown that the rings whose simple-direct-injective right modules are simple-direct-projective are exactly the left perfect right H-rings, and that, for a commutative Noetherian ring, simple-direct-projective modules are simple-direct-injective if and only if simple-direct-injective modules are simple-direct-projective if and only if the ring is Artinian. These results are recently appeared in [1].

A catchy line for my "amenability and congeniality" talk today: "All bases are created equal but some are more equal than others"... :-)
Something to put in my "to-do" list: ask these guys to sing "my favorite rings."
