Abstract

In this work, we prove a fixed-point theorem in the variable exponent spaces ℓ_p(.), when p⁻ = 1 without further conditions. This result is new and adds more information regarding the modular structure of these spaces. To be more precise, our result concerns ρ-nonexpansive mappings defined on convex subsets of ℓ_p(.) that satisfy a specific condition which we call “condition of uniform decrease”.
