Then M is a gr – comultiplication module if and only if M is gr – strongly self-cogenerated. Then the following hold: Let R be a G -graded ring and M an R -module.

### Some properties of graded comultiplication modules : Open Mathematics

Let R be a G -graded commutative ring and M a graded R -module. A graded R -module M is said to be gr – simple if 0 and M are its only graded mldules.
