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 .enF -cosmall quotients, right minimal morphisms, F -superfluous quotientsOn F -cosmall morphismsArticle7149689771303-5991
