Abstract
Let be a semiring. An -semimodule is called a multiplication semimodule if for each subsemimodule of there exists an ideal of such that . In this paper we investigate some properties of multiplication semimodules and generalize some results on multiplication modules to semimodules. We show that every multiplicatively cancellative multiplication semimodule is finitely generated and projective. Moreover, we characterize finitely generated cancellative multiplication -semimodules when is a yoked semiring such that every maximal ideal of is subtractive.
