Approximation for fixed points of asymptotically nonexpansive mappings. (English) Zbl 0734.47037

The author studies the convergence of the iteration sequence \(z_{n+1}=\mu_{n+1}T^ n(z_ n),\) where T is an asymptotically nonexpansive self-mapping of a nonempty closed, bounded, and starshaped subset of a smooth reflexive Banach space. Related previous work is due to K. Goebel, B. Halpern, W. A. Kirk, and P. Vijayaraju [e.g. Bull. Calcutta Math. Soc. 80, No.2, 133-136 (1988; Zbl 0667.47032)].
