Abstract of a paper by Yisheng Song, Rudong Chen
This is an announcement for the paper “Pazy's fixed point theorem with respect to the partial order in uniformly convex Banach spaces” by Yisheng Song<http://arxiv.org/find/math/1/au:+Song_Y/0/1/0/all/0/1>, Rudong Chen<http://arxiv.org/find/math/1/au:+Chen_R/0/1/0/all/0/1>. Abstract: In this paper, the Pazy's Fixed Point Theorems of monotone $\alpha$−nonexpansive mapping $T$ are proved in a uniformly convex Banach space $E$ with the partial order "$\leq$". That is, we obtain that the fixed point set of $T$ with respect to the partial order "$\leq$" is nonempty whenever the Picard iteration $\{T^n x_0\}$ is bounded for some initial point $x_0$ with $x_0\leq Tx_0$ or $Tx_0\leq x_0$. When restricting the demain of $T$ to the cone $P$, a monotone $\alpha$−nonexpansive mapping $T$ has at least a fixed point if and only if the Picard iteration $\{T^n0\}$ is bounbed. Furthermore, with the help of the properties of the normal cone $P$, the weakly and strongly convergent theorems of the Picard iteration $\{T^n x_0\}$ are showed for finding a fixed point of $T$ with respect to the partial order "$\leq$" in uniformly convex ordered Banach space.
