In this article we introduce the concepts of lacunary Iconvergent sequences. We investigate its different properties like solid, symmetric, convergence free etc.

This work is concerned with several important different types of convergence that will be described on neutrosophic normed spaces. In the study, arithmetic was combined statistical and then integrated into structure neutrophic spaces established through membership function. For this purpose, in space, firstly, some definitions can lacunary sequence, ideal structures convergent, concepts are giv...

In this paper, we study the concepts of Wijsman Cesàro summability and Wijsman lacunary convergence of double sequences of sets and investigate the relationship between them.
