## New type of difference sequence spaces of fuzzy real numbers.(English)Zbl 1190.46008

Summary: We introduce the natation difference operator $$\Delta_m$$ ($$m\geq 0$$, an integer) for studying properties of some sequence spaces. We define the sequence spaces $$\ell^F_\infty(\Delta_m)$$, $$c^F(\Delta_m)$$, $$c_0^F(\Delta_m)$$, and investigate their properties like solidness, convergence free, symmetricity, completeness.
