Abstract
We provide some characterizations of rings R for which every (finitely generated) module belonging to a class \(\cal{C}\) of R-modules is a direct sum of cyclic submodules. We focus on the cases, where the class \(\cal{C}\) is one of the following classes of modules: semiartinian modules, semi-V-modules, V-modules, coperfect modules and locally supplemented modules.
