When does an AB5* module have finite hollow dimension?

Derya Keskin Tütüncü; Rachid Tribak; Patrick F. Smith — 2011

Colloquium Mathematicae

Using a lattice-theoretical approach we find characterizations of modules with finite uniform dimension and of modules with finite hollow dimension.

Direct sums of semi-projective modules

Derya Keskin Tütüncü; Berke Kaleboğaz; Patrick F. Smith — 2012

Colloquium Mathematicae

We investigate when the direct sum of semi-projective modules is semi-projective. It is proved that if R is a right Ore domain with right quotient division ring Q ≠ R and X is a free right R-module then the right R-module Q ⊕ X is semi-projective if and only if there does not exist an R-epimorphism from X to Q.
