✦ Synopsis


Let K be a nonempty closed convex proper subset of a real uniformly convex and uniformly smooth Banach space E; T : K-E be an asymptotically weakly suppressive, asymptotically weakly contractive or asymptotically nonextensive map with F ðTÞ :¼ fxAK: Tx ¼ xga|: Using the notion of generalized projection, iterative methods for approximating fixed points of T are studied. Convergence theorems with estimates of convergence rates are proved. Furthermore, the stability of the methods with respect to perturbations of the operators and with respect to perturbations of the constraint sets are also established.

Ahmad and Imdad and Ahmed and Khan have studied coincidences and fixed points of nonself hybrid contractions on metrically convex spaces. However, most of their main theorems contain errors and admit counterexamples. In this paper, we rectify these results and obtain coincidence and fixed point theo

In this paper, a strong convergence theorem for asymptotically nonexpansive mappings in a uniformly convex and smooth Banach space is proved by using metric projections. This theorem extends and improves the recent strong convergence theorem due to Matsushita and Takahashi [S. Matsushita, W. Takahas
