Abstract: In this article we introduce the notion of relative uniform convergence of difference double sequence of positive linear functions. We define the difference double sequence spaces $$_2\ell _\infty (\varDelta , ru),~ _2c(\varDelta , ru),~ _2c_0(\varDelta… read more here.

Abstract: We present double sequence spaces of fuzzy numbers defined using fractional difference operator and Musielak–Orlicz function. Some topological properties for these spaces are presented and some inclusion relations are established. Finally, we formulate and prove… read more here.
