We introduce the sequence spaces [ ˆ w(M)] and [ ˆ w(M)] θ of strong almost convergence and lacunary strong almost convergence respectively defined by the Orlicz function M. We establish certain inclusion relations and show that the above spaces are same for any bounded sequences. 1. Definitions and notations A sequence x ∈ l ∞ , the space of bounded sequences x = (x k), is said to be almost co...

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...

The study of minimal complements in a group or semigroup was initiated by Nathanson. notion and being complement leads to the co-minimal pairs which considered prior work authors. In this article, we type subsets integers free abelian groups higher rank can be part pair. We show that majority lacunary sequences have property. From conditions established, one any infinite subset finitely generat...
