In Section 2, we present various properties of these modules. In Section 3, we examine the characterization of modules over commutative domains. In Section 4, we explore the concept of (R)-Rad-cc-supplemented modules, which generalizes a generalized notion of (R)-co-coatomically-supplemented modules in R. Alizade, S. G & uuml;ng & ouml;r (2018). A module W is (R)-Rad-cc-supplemented if each co-coatomic A W is of a Rad-supplement which is a direct summand of W. In the concluding section of this paper, we investigate into its characteristics by introducing Rad-cc-semiperfect modules.eninfo:eu-repo/semantics/openAccessco-coatomic submodulesRad-cc-supplemented modulestotally Rad-cc-supplemented modulesArticle10.21136/MB.2025.0053-24Q3WOS:001706664600001Q4
