  • The Injective Profile of a Ring and its Effect on the Structure of Rings 

    Yuca, Nergiz (Fen Bilimleri Enstitüsü, 2020)
    This thesis is partly based on recent developments on the subject of what is known as “injectivity domains” in the theory of modules over rings with identity. The subject was suggested as a measurement of how far a module ...
