Abstract

In this study, for double set sequences, we introduced the notions of invariant and lacunary invariant statistical convergence of order $\eta$ ($0<\eta\leq 1$) in the Wijsman sense. Also, we investigated the inclusion relations between them.

Keywords

Double lacunary sequence, invariant statistical convergence, order $\eta$, double set sequences, convergence in the Wijsman sense
