As a mean to provide intrinsic characterizations of poor modules, the notion of a pauper
module is introduced. A module is a pauper if it is poor and has no proper poor direct …

Let R be a commutative ring with identity. A short exact sequence E of R-modules is said to
be neat (respectively, P-pure) if the sequence Hom R (S, E)(respectively, S⊗ RE) is exact for …

R birimli asosyatif bir halka olsun ve M bir sağ R-modül olsun. N, M'nin bir alt modülü olsun.
Eğer Z2 (N)= N ise, N ye M'nin S-bütünleyen alt modülü denir. S-bütünleyen alt modüller …

In this thesis we consider some problems and also generalize some results related to
indigent modules and subinjectivity domains. We prove that subinjectivity domain of any …
