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.

Abstract: In 1996, M. Stojaković and Z. Stojaković examined the convergence of a sequence of fuzzy numbers via Zadeh’s Extension Principle, which is quite difficult for practical use. In this paper, we utilize the notion λ−level… read more here.
