Özet

Let R be a ring. A collection of R-modules containing the zero module and closed under isomorphisms will be denoted by X. An R-module M is said to be X -lifting if for every X-submodule N of M there exists A <= N such that M = A circle plus B and N boolean AND B is small in B [11]. In the present paper, we consider the question:
