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 ...

On Ray's theorem for weak firmly nonexpansive mappings in Hilbert Spaces [PDF]
, 2016 In this work, we introduce notions of generalized firmly nonexpansive (G-firmly non expansive) and fundamentally firmly nonexpansive (F-firmly nonexpansive) mappings and utilize to the same to prove Ray's theorem for G-firmly and F-firmly nonexpansive ...

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.

Nonexpansive Mappings in Locally Convex Spaces [PDF]
Canadian Mathematical Bulletin, 1977 Recently Bruck initiated the study of the structure of the fixed-point set of a nonexpansive selfmap T of a Banach space, where T satisfies a conditional fixed point property. We generalize many of his results to a Hausdorff locally convex space X. Also, we generalize a result of Holmes and Narayanaswami and use it, along with a procedure of Kiang, to ...

Journal of Function Spaces, Volume 2026, Issue 1, 2026.The present paper develops a new two‐step iterative method, referred to as the P∗ iteration, for the approximation of fixed points of weak contractions mappings in Banach spaces. The theoretical analysis establishes the strong convergence of the proposed scheme to the unique fixed point, along with its almost I‐stability.

Strong convergence theorems for a sequence of nonexpansive mappings with gauge functions
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013 In this paper, we first prove a path convergence theorem for a nonexpansive mapping in a reflexive and strictly convex Banach space which has a uniformly Gˆateaux differentiable norm and admits the duality mapping jφ, where φ is a gauge function on [0,∞).

On firmly nonexpansive mappings [PDF]
Proceedings of the American Mathematical Society, 1991 The author proves the following. Let X be a uniformly convex Banach space, \(C=C_ 1\cup C_ 2\cup...\cup C_ n\) a union of nonempty, bounded, closed and convex subsets of X, and T: \(C\to C\) a mapping such that \[ \| Tx-Ty\| \leq \| (1-\lambda)(x-y)+\lambda (Tx-Ty)\| \quad (x,y\in C), \] for some \(\lambda\in (0,1)\). Then T has a fixed point in C.

Fixed Point Property for Nonexpansive Mappings and Reflexivity: A Hilbert C∗‐Module Approach
Journal of Function Spaces, Volume 2026, Issue 1, 2026.We prove that for any infinite‐dimensional Hilbert space H, there exists a sequence of infinite‐dimensional, full Hilbert C∗‐modules over K(H)—the C∗‐algebra of compact operators on H—each of which is isomorphic to H and has the fixed point property for nonexpansive mappings (FPP).

Strong Convergence Theorems for a Countable Family of Nonexpansive Mappings in Convex Metric Spaces
Abstract and Applied Analysis, 2011 We introduce a new modified Halpern iteration for a countable infinite family of nonexpansive mappings {Tn} in convex metric spaces. We prove that the sequence {xn} generated by the proposed iteration is an approximating fixed point sequence of a ...
