Periodic Points of Modular Firmly Mappings in the Variable Exponent Sequence Spaces ℓp(·)

Abstract

In this work, we investigate the existence of periodic points of mappings defined on nonconvex domains within the variable exponent sequence spaces ℓp(·). In particular, we consider the case of modular firmly nonexpansive and modular firmly asymptotically nonexpansive mappings. These kinds of results have never been obtained before.
