A Picard-Mann hybrid iterative process

TLDR: In this article, a hybrid of Picard and Mann iterative processes is proposed, which converges faster than all of Picard, Mann, and Ishikawa iterative process in the sense of Berinde (Iterative Approximation of fixed points, 2002) for contractions.

Abstract: We introduce a new iterative process which can be seen as a hybrid of Picard and Mann iterative processes. We show that the new process converges faster than all of Picard, Mann and Ishikawa iterative processes in the sense of Berinde (Iterative Approximation of Fixed Points, 2002) for contractions. We support our analytical proof by a numerical example. We prove a strong convergence theorem with the help of our process for the class of nonexpansive mappings in general Banach spaces and apply it to get a result in uniformly convex Banach spaces. Our weak convergence results are proved when the underlying space satisfies Opial’s condition or has Frechet differentiable norm or its dual satisfies the Kadec-Klee property.
