Some fixed-point theorems for a pair of Reich-Suzuki-type nonexpansive mappings in hyperbolic spaces

Topological Algebra and its Applications, 2023
In this article, we prove some fixed-point results for a pair of Reich-Suzuki-type nonexpansive mappings in uniformly convex WW-hyperbolic spaces. We introduce a new iterative scheme and establish its convergence to the fixed points of a pair of Reich ...

On directionally nonexpansive mappings

European Journal of Mathematics
AbstractIn 2000, W.A. Kirk introduced the concept of directionally nonexpansive mappings. Here, we present a more comprehensive study of this class of mappings, including a fixed-point result for them. We further present a class of mappings, properly containing the directionally nonexpansive ones, for which Kirk’s theorem still holds.

A Depth‐Ordered Forwarding Game With Niche‐Confined Evolutionary Recovery for Energy‐Efficient Underwater Wireless Sensor Networks

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Underwater wireless sensor networks operate under scarce acoustic bandwidth, long propagation delay, depth‐dependent attenuation, and a fixed energy budget that is rarely replenished. We propose the Hawk–Dove Game Optimization Algorithm with Elite Niche Clone Evolutionary Computing (HDGOA‐ENCEC), a routing protocol that couples a depth‐ordered ...

Modified Iterative Algorithms for Nonexpansive Mappings [PDF]

International Journal of Stochastic Analysis, 2009
Let H be a real Hilbert space, let S, T be two nonexpansive mappings such that F(S)∩F(T) ≠ ∅, let f be a contractive mapping, and let A be a strongly positive linear bounded operator on H. In this paper, we suggest and consider the strong converegence analysis of a new two‐step iterative algorithms for finding the approximate solution of two ...

A Nonlinear Quantum‐Deformation‐Fractional Model for Memory‐Dependent Glucose–Insulin–Glucagon Dynamics With Real‐Data Validation

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This study develops a nonlinear (q, τ)‐fractional biophysical model for memory‐dependent glucose–insulin–glucagon regulation. The model is motivated by the fact that metabolic regulation is governed by delayed insulin action, counter‐regulatory glucagon response, nonlinear feedback, and scale‐dependent physiological adaptation.

Strong convergence theorems for infinite families of nonexpansive mappings in general Banach spaces

Fixed Point Theory and Applications, 2005
In 1979, Ishikawa proved a strong convergence theorem for finite families of nonexpansive mappings in general Banach spaces. Motivated by Ishikawa's result, we prove strong convergence theorems for infinite families of nonexpansive mappings.

Convergence of Picard–CR Iterative Algorithm and Applications

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In applied mathematics, graph theory (GT) is a notably compelling area of study. In the last 50 years, the number of mathematicians making contributions to research in this field has consistently increased. This rising interest is mainly a result of the significant real‐world applications it offers.
