Abstract

We introduce the notions of M-pjective modules. We show that relative pjectivity is necessary and sufficient for a direct sum of two lifting modules to be lifting. We also introduce the new concept of generalized lifting modules, and give some properties of such modules in analogy with the know properties for lifting modules.
