Decompositions of D1 Modules,l-extending (D1) modules, those modules which are supplemented and for which each supplement is a summand. The notions of hollowness and dual Goldie dimension play a prominent role. Our results are analogous to results for extending modules developed by Camillo and Yousif.

On Extensions of Regular Rings of Finite Index by Central Elements,h is “almost biregular”, i.e., one where supports of elements in the Pierce sheaf are open. It is formed by adjoining certain central idempotents from .. Extensions of . by central elements, particularly idempotents, are examined. Many examples and counterexamples are presented.

Weak Relative Injective ,-Subgenerated Modules,weakly .-injective in .[.]. Modules for which every submodule is weakly injective (tight) in .[.] are characterized. Modules . for which every module in .[.] is weakly injective and for which weakly injective modules are closed under direct sums are studied.

Direct Product and Power Series Formations Over 2-Primal Rings,e sufficient conditions on the rings for their direct product to be 2-primal. We also show that the ring of formal power series over a 2-primal ring (or even a ring satisfying (PS I)) need not be 2-primal.
