    On F -cosmall morphisms
    (Ankara Üniversitesi, 2022) Tütüncü, Derya Sezgin; Other; Other
    In this paper, we first define the notion of F -cosmall quotient for an additive exact substructure F of an exact structure E in an additive category A . We show that every F -cosmall quotient is right minimal in some cases. We also give the definition of F -superfluous quotient and we relate it the approximation of modules. As an application, we investigate our results in a pure-exact substructure F .
