Wijsman I-invariant convergence of sequences of sets

Abstract

In this paper, we study the concepts of Wijsman I-invariant convergence (I^W_σ ), Wijsman I*-invariant convergence (I*^Wσ ), Wijsman p-strongly invariant convergence ([W Vσ]p) of sequences of sets and investigate the relationships between Wijsman invariant convergence, [W Vσ]p, IWσ and I*WσAlso, we introduce the concepts of IWσ -Cauchy sequence and I*Wσ -Cauchy sequence of sets.
