Wijsman quasi-invariant convergence

Abstract

In this study, we defined concepts of Wijsman quasi-invariant convergence, Wijsman quasi-strongly invariant convergence and Wijsman quasi-strongly q-invariant convergence. Also, we give the concept of Wijsman quasi-invariant statistically convergence. Then, we study relationships among these concepts. Furthermore, we investigate relationship between these concepts and some convergence types given earlier for sequences of sets, too.
