Abstract
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
.
