Analysis in Theory and Applications, 2011 Summary: The main purpose of this paper is to prove a collection of new fixed point theorems and existence theorems for the nonlinear operator equation \(F (x)=\alpha x\) (\(\alpha\geq 1\)) for so-called 1-set weakly contractive operators on unbounded domains in Banach spaces.

Plastic Behavior and Design Methodology for Curved Members in Seismic Applications
JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.This study investigated the plastic behavior of curved members through static analysis and extensive parametric studies, focusing on initial elastic stiffness, plastic strength, slenderness effects, and section compactness. Estimation equations were developed and validated, contributing to the development of a connection design methodology that ...

On Convergence of a Family of Random Walks in the Infinite Dimensional Stiefel Manifold
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.In this paper, we study random walks taking values in an infinite‐dimensional space—either a Hilbert space or an infinite‐dimensional manifold embedded in it, such as the Stiefel manifold. These random walks arise in problems in shape theory, particularly when stochastic optimization is applied.

Some Paranormed Sequence Spaces Which Involve Arithmetic Divisor Sum Function
Journal of Function Spaces, Volume 2026, Issue 1, 2026.Let Dr, r ≥ 0, be a triangle and q = (qj) be a bounded sequence of strictly positive numbers. In this paper, we study the algebraic and topological properties of the paranormed sequence space ℓDr,q, generated by the triangle Dr over Maddox′s space ℓ(q). We identify the Schauder basis as well as the α‐, β‐, and γ‐duals of the space ℓDr,q. One section is

Uniformly Continuous Functionals and Operators Commuting with Lebesgue–Fourier Algebras
Journal of Function Spaces, Volume 2026, Issue 1, 2026.Let G be a locally compact group. This paper investigates the space of uniformly continuous functionals associated with the Lebesgue–Fourier algebra on G. Our aim is to describe the dual of this space in terms of bounded operators on the dual of the Lebesgue–Fourier algebra that commute with the natural module action, and to determine exactly when this

Taut Foliations and ℝ‐Covered Foliations With Transverse Measure on 3‐Manifolds
Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, we establish a theorem that provides sufficient conditions for a taut foliation on closed 3‐manifolds to be, up to monotone equivalence, a perturbation of a fibration. We also give some conditions under which a taut foliation is ℝ‐covered.

Acoustic waves interacting with non–locally reacting surfaces in a Lagrangian framework
Mathematische Nachrichten, Volume 298, Issue 12, Page 3855-3892, December 2025.Abstract The paper deals with a family of evolution problems arising in the physical modeling of small amplitude acoustic phenomena occurring in a fluid, bounded by a surface of extended reaction. They are all derived in a Lagrangian framework. We study well‐posedness of these problems, their mutual relations, and their relations with other evolution ...

Clinical and Translational Science, Volume 18, Issue 12, December 2025.ABSTRACT Proteomics can identify pharmacodynamic (PD) biomarkers by detecting protein changes in response to drug treatment, providing insights into drug mechanism and biological effects. In this study, we profiled over 7000 plasma proteins to identify potential PD biomarkers for the interleukin‐5 (IL‐5) inhibitors mepolizumab and reslizumab, which are

Boundary representations of locally compact hyperbolic groups
Proceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.Abstract We develop the theory of Patterson–Sullivan measures for locally compact hyperbolic groups. This theory associates to certain left‐invariant metrics on the group measures on its boundary. Next, we establish irreducibility of the resulting (unitary) Koopman representations for second countable, nonelementary, unimodular locally compact ...
