Abstract
In this article, we define the notion of relative uniform convergence of fractional difference sequence of the function space rumϕ(∆ᵅ, p), where p ≥ 0. We established many attributes of rumϕ(∆ᵅ, p), including solidity, symmetry, completeness, convergence-free, sequence algebra, and convex characteristics. The relative uniform fractional difference of p− absolutely summable, bounded, convergent, null sequence of function spaces was also introduced. These are represented by the notations ℓp(∆ᵅru), ℓ∞(∆ᵅru), c(∆ᵅru), c0(∆ᵅru), and their relationship to the space rumϕ(∆ᵅ, p) is reviewed.
