On Coatomic Semimodules over Commutative Semirings

Abstract

This paper generalizes some well known results on coatomic and semisimple modules in commutative rings to coatomic and semisimple semimodules over commutative semirings. The main difficulty is figuring out what additional hypotheses the subsemimodules must satisfy to get similar results. It is proved that k-subsemimodules of semimodules are important in the study of semimodules.
