Sozen, Esra Ozturk2025-03-232025-03-2320201225-293X2288-6176https://doi.org/10.5831/HMJ.2020.42.3.511https://hdl.handle.net/11486/4496A module M is called cofinitely closed weak delta-supplemented (briefly delta-ccws-module) if for any cofinite closed submodule N of M has a weak delta-supplement in M: In this paper we investigate the basic properties of delta-ccws modules. In the light of this study, we can list the main facts obtained as following: (1) Any cofinite closed direct summand of a delta-ccws module is also a delta-ccws module; (2) Let R be a left delta-V-ring. Then R is a delta-ccws module iff R is a ccws-module iff R is extending; (3) Any nonsingular homomorphic image of a delta-ccws-module is also a delta-ccws-module; (4) We characterize nonsingular delta-V-rings in which all nonsingular modules are delta-ccws.eninfo:eu-repo/semantics/closedAccessCofinite submoduleclosed submoduleextending modulerefinable moduleclosed weak ffi-supplemented moduleccws-moduleArticle42351152010.5831/HMJ.2020.42.3.511N/AWOS:000589402200006N/A
