Projective and injective semimodules over semirings
In this thesis general notions of projectivity and injectivity for semimodules are defined. This is done by introducing what we call k-projective and i-injective semimodules. The concepts of cogenerator and flatness have also been introduced. In chapter I we give an equivalent definition to projecti...
