Wijsman quasi-invariant convergence

Abstract

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