Abstract:Suppose $E$ is a real uniformly smooth Banach space, $K$ is a nonempty closed convex and bounded subset of $E$, and $T:Kto K$ is a strong pseudo-contraction. It is proved that if $T$ has a fixed point in $K$ then both the Mann and the Ishikawa iteration processes, for an arbitrary initial vector in $K$, converge strongly to the unique fixed $T$. No continuity assumption is necessary for this convergence. Moreover, our iteration parameters are independent of the geometry of the underlying Banach space and of any property of the operator.

Keywords:Strong pseudocontractions   accretive operators   uniformly smooth Banach spaces   duality map
