| Abstract: | In this paper, we principally introduce the concept of Nκ-projective semimodules, combining the theories of projective modules and projective semimodules with Nκ-projective semimodules,we get some properties of Nκ-projective semimodules, which are the generalization of some properties of projective modules and projective semimodules. |
