Subinvariant Metric Functionals for Nonexpansive Mappings

open access: yesNumerical Functional Analysis and Optimization
We investigate the existence of subinvariant metric functionals for commuting families of nonexpansive mappings in noncompact subsets of Banach spaces. Our findings underscore the practicality of metric functionals when searching for fixed points of nonexpansive mappings.
