Convergence results on Picard-Krasnoselskii hybrid iterative process in CAT(0) spaces

open access: yesOpen Mathematics, 2021
We get the strong and Δ\Delta -convergence of the Picard-Krasnoselskii hybrid iteration scheme to a fixed point of a self-map endowed with the condition (Bγ,μ)\left({B}_{\gamma ,\mu }). We use the nonlinear context of CAT(0) spaces for establishing these

The Convergence of Three-Step Iterative Schemes for Generalized Φ−Hemi-Contractive Mappings and the Comparison of Their Rate of Convergence

open access: yesJournal of Mathematics, 2021
Charles proved the convergence of Picard-type iteration for generalized Φ−accretive nonself-mappings in a real uniformly smooth Banach space. Based on the theorems of the zeros of strongly Φ−quasi-accretive mappings and fixed points of strongly Φ−hemi ...

Picard Iterations for Diffusions on Symmetric Matrices [PDF]

open access: yesJournal of Theoretical Probability, 2015
Matrix-valued stochastic processes have been of significant importance in areas such as physics, engineering and mathematical finance. One of the first models studied has been the so-called Wishart process, which is described as the solution of a stochastic differential equation in the space of matrices.

On New Picard-Mann Iterative Approximations with Mixed Errors for Implicit Midpoint Rule and Applications

open access: yesJournal of Function Spaces, 2019
In order to solve (partial) differential equations, implicit midpoint rules are often employed as a powerful numerical method. The purpose of this paper is to introduce and study a class of new Picard-Mann iteration processes with mixed errors for the ...

New approximation methods for solving elliptic boundary value problems via Picard-Mann iterative processes with mixed errors

open access: yesBoundary Value Problems, 2017
In this paper, we introduce and study a class of new Picard-Mann iterative methods with mixed errors for common fixed points of two different nonexpansive and contraction operators.

Strongly Convergence of Two Iterations For a Common Fixed Point with an Application

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2019
     In this paper, we study some cases of a common fixed point theorem for classes of firmly nonexpansive and generalized nonexpansive maps. In addition, we establish that the Picard-Mann iteration is faster than Noor iteration and we used Noor ...

Sharp estimation of local convergence radius for the Picard iteration [PDF]

open access: yes, 2018
We investigate the local convergence radius of a general Picard iteration in the frame of a real Hilbert space. We propose a new algorithm to estimate the local convergence radius.

Using the unstable manifold correction in a Picard iteration to solve the velocity field in higher-order ice-flow models [PDF]

open access: yes, 2010
We address the usefulness of the unstable manifold correction (UMC) in a Picard iteration for the solution of the velocity field in higher-order ice-flow models. We explain under-and overshooting and how one can remedy them. We then discuss the rationale
