Inertial algorithm with self-adaptive step size for split common null point and common fixed point problems for multivalued mappings in Banach spaces

Optimization, 2021
In this article we introduce an inertial iterative scheme with self-adaptive step size for finding a common solution of split common null point problem for a finite family of maximal monotone operators and fixed point problem for a finite family of ...

A simple strong convergent method for solving split common fixed point problems

Journal of Nonlinear and Variational Analysis, 2021
. In this paper, we study the split common fixed point problem for demicontractive mappings in real Hilbert spaces. We propose an alternative regularization scheme with a self-adaptive step size for solving the problem and prove its strong convergence ...

Two Projection Methods for Solving the Split Common Fixed Point Problem with Multiple Output Sets in Hilbert Spaces

, 2021
We study the split common fixed point problem with multiple output sets in Hilbert spaces. In order to solve this problem, we propose two new algorithms and establish two strong convergence theorems for both of them.

Common supports as fixed points

Geometriae Dedicata, 1996
A family \({\mathcal S}\) of subsets of \(\mathbb{R}^d\) is called by the authors sundered if, for any way of choosing a point from \(r (\leq d + 1)\) members of \({\mathcal S}\), the chosen \(r\) points are affinely independent. The authors mention that this is equivalent to being \((d - 1)\)-separated as defined by \textit{S. Cappell}, \textit{J.

General Common Fixed Point Theorems for Compatible Mappings of Type (C)

Sarajevo Journal of Mathematics
In this note, we prove a common fixed point theorem for four compatible mappings of type (C) satisfying an implicit relation. This theorem generalizes, improves and extends the result of Popa [6] and others.

Parallel Iterative Methods for Solving the Split Common Fixed Point Problem in Hilbert Spaces

Numerical Functional Analysis and Optimization, 2019
We introduce three new parallel algorithms for solving the split common fixed point problem in Hilbert spaces. Those iterative methods for solving split common fixed point problems which involve step sizes that depend on the norm of a given bounded ...

Common fixed point theorems under rational contractions for a pair of mappings in bicomplex valued metric spaces

Journal of Interdisciplinary Mathematics, 2019
In this paper, we have proved some common fixed point theorems for a pair of mappings satisfying certain rational contraction condition in the frame work of bicomplex valued metric space (X, d). We have also defined the max function for the partial order
