WebJan 4, 2024 · Then T is a fixed point free nonexpansive mapping on K. Also, the sequence of iterates (the Picard sequence) of a nonexpansive mapping may not converge to a fixed point of the mapping, unlike the contraction mappings. Therefore the study of existence and convergence of fixed points of nonexpansive mappings is an important subject.
