Asymptotically nonexpansive mappings

Nonlinear Analysis: Theory, Methods & Applications, 1998
This is a very interesting paper. The method used suggests an entirely new approach in the study of fixed points and related properties of asymptotically nonexpansive mappings. Let \(E\) be a Banach space and \(D\subseteq E\). We recall, if there exists a sequence of reals \(\{k_i\}\) with \(k_i\downarrow 1\) such that \(\|T^ix- T^iy\|\leq k_i\|x-y\|\)

A Remark on Nonexpansive Mappings

Canadian Mathematical Bulletin, 1981
Let X be a closed convex subset of a Banach space and let T: X → X be a nonexpansive mapping, i.e.
