On direct sums of lifting modules and internal exchange property
W Dejun - Kyungpook Mathematical Journal, 2006 - koreascience.kr
Let R be a ring with identity and let $ M= M_1 {\bigoplus} M_2 $ be an amply supplemented
R-module. Then it is proved that $ M_i $ has ($ D_1 $) and is $ M_j-^* ojective $ for $ i {\neq} …

A generalization of the class of principally lifting modules
Let 𝑅 be an arbitrary ring with identity and 𝑀 a right 𝑅-module. In this paper, we introduce a
class of modules which is analogous to that of Goldie*-lifting and principally Goldie*-lifting …

CHARACTERIZATIONS OF LIFTING MODULES IN TERMS OF COJECTIVE MODULES AND THE CLASS OF ℬ (M, X)
N Orhan, DK TÜTÜNCÜ - International Journal of Mathematics, 2005 - World Scientific
In this note, we introduce the (small, pseudo-) ℬ (M, X)-cojective modules and we generalize
(small, pseudo-) cojective modules via the class ℬ (M, X). Let M= M1⊕ M2 be an X-amply …

Modules which are lifting relative to module classes
M KOŞAN, A Harmanci - Kyungpook Mathematical Journal, 2008 - avesis.hacettepe.edu.tr
In this paper, we study a module which is lifting and supplemented relative to a module
class. Let R be a ring, and let X be a class of R-modules. We will define X-lifting modules …

[引用][C] On direct sums of extending modules and internal exchange property
K Hanada, Y Kuratomi, K Oshiro - Journal of Algebra, 2002 - Elsevier
An R-module M is called an extending module, and also called CS, if it satisfies the following
full extending property: For any submodule X of M, there exists a direct summand X∗ of M …
