Kannan Nonexpansive Mappings on Variable Exponent Function Space of Complex Variables with Some Applications

open access: yesJournal of Function Spaces, 2022
This paper establishes the reality of a fixed point of Kannan’s prequasinorm contraction mapping on the variable exponent function space of complex variables, demonstrating that it satisfies the property (R) and possesses a prequasinormal structure.
