Totally weak supplemented modules
The main purpose of this thesis is to give a survey about some classes of modules including supplemented, weakly supplemented, totally supplemented and totally weak supplemented modules over commutative Noetherian rings, in particular over Dedekind domains based on results of H. Zöschinger, P. Rudlof and P. F. Smith. A module is weakly supplemented if and only if the factor of that module by a finite direct sum of its hollow submodules is weakly supplemented. A module is weakly supplemented (totally weak supplemented) if and only if the factor of it by a linearly compact submodule is weakly supplemented (totally weak supplemented).
