Abstract
The results for abelian groups can be generalized for modules after imposing some conditions on modules/rings. Here the rings are almost restriction free and the \( QTAG \)-modules satisfy a simple condition. In this paper essentially finitely indecomposable modules are studied with the help of \(h\)-pure and nice submodules and socles. \(HT\)-modules were defined by Mehdi et al. (On \(HT\)-modules, To appear in GAMS, 2015) and here we investigate the relation between \(HT\)-modules and essentially finitely indecomposable modules.
