On projective QTAG-modules

F. Sikander

In this paper we introduce the new class of QTAG-modules namely ω1-(ω+n)-projective modules, which is an amalgamation of three important classes of modules: n-bounded modules, the direct sum of uniserial modules and the countably generated modules. This class is given many equivalent characterizations including being the smallest class containing the (ω+n)-projective modules that is closed with respect to ω1-bijective homomorphisms.
