Journal Article
In this paper, we introduce a new three-step iteration scheme and establish convergence results for approximation of fixed points of nonexpansive mappings in the framework of Banach space. Further, we show that the new iteration process is faster than a number of existing iteration processes. To support the claim, we consider a numerical example and approximated the fixed point numerically by computer using MATLAB.

Journal Article
Self-adaptive algorithms are presented for solving the split common fixed point problem of demicontractive operators in Hilbert spaces. Weak and strong convergence theorems are given under some mild assumptions.

Tayyab KamranMihai PostolacheAn existence theorem for Volterra-type integral inclusion is establish in b-metric spaces. We first introduce two new F-contractions of Hardy–Rogers type and then establish fixed point theorems for these contractions in the setting of b-metric spaces. Finally, we apply our fixed point theorem to prove the existence theorem for Volterra-type integral inclusion. We also provide an example to show that our fixed point theorem is a proper generalization of a recent fixed point theorem by Cosentino et al.

Journal Article
In this article, we present tripled coincidence point theorems for F: X3 → X and g: X → X satisfying weak φ-contractions in partially ordered metric spaces. We also provide nontrivial examples to illustrate our results and new concepts presented herein. Our results unify, generalize and complement various known comparable results from the current literature, Berinde and Borcut and Abbas et al.
About Me
Mihai Postolache received his PhD degree in mathematics from Babes-Bolyai University, Cluj-Napoca, Romania. Currently, he is a professor at the Department of Mathematics and Computer Science at the University Politehnica of Bucharest and has been the head of the department since 2012. He is also a senior researcher at the Institute of Mathematical Statistics and Applied Mathematics of the Romanian Academy. He has published over one hundred research papers in selective journals, specialized in fixed point theory, nonlinear analysis, numerical algorithms, and nonlinear optimization. Professor Postolache serves as a member of several editorial boards of some international journals. He was awarded three times (in 2016, 2017, and 2020) by Clarivate Analytics as one of the highly cited researchers in the field of mathematics.
