Abstract

In this paper, the Pazy's Fixed Point Theorems of monotone α\alpha-nonexpansive mapping TT are proved in a uniformly convex Banach space EE with the partial order "\leq". That is, we obtain that the fixed point set of TT with respect to the partial order "\leq" is nonempty whenever the Picard iteration {Tnx0}\{T^nx_0\} is bounded for some initial point x0x_0 with x0Tx0x_0\leq Tx_0 or Tx0x0Tx_0\leq x_0. When restricting the demain of TT to the cone PP, a monotone α\alpha-nonexpansive mapping TT has at least a fixed point if and only if the Picard iteration {Tn0}\{T^n0\} is bounbed. Furthermore, with the help of the properties of the normal cone PP, the weakly and strongly convergent theorems of the Picard iteration {Tnx0}\{T^nx_0\} are showed for finding a fixed point of TT with respect to the partial order "\leq" in uniformly convex ordered Banach space.
