Nonradial solutions for the critical quasi‐linear Hénon equation involving p$p$‐Laplacian in RN$\mathbb {R}^N$

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract In this paper, we investigate the following D1,p$D^{1,p}$‐critical quasi‐linear Hénon equation involving p$p$‐Laplacian −Δpu=|x|αupα∗−1,x∈RN,$$\begin{equation*} -\Delta _p u=|x|^{\alpha }u^{p_\alpha ^*-1}, \qquad x\in \mathbb {R}^N, \end{equation*}$$where N⩾2$N\geqslant 2$, 1

Moduli and Characteristics of Monotonicity in Some Banach Lattices

open access: yesFixed Point Theory and Applications, 2010
First the characteristic of monotonicity of any Banach lattice X is expressed in terms of the left limit of the modulus of monotonicity of X at the point 1.

Exact local distribution of the absolutely continuous spectral measure

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract It is well‐established that the spectral measure for one‐frequency Schrödinger operators with Diophantine frequencies exhibits optimal 1/2$1/2$‐Hölder continuity within the absolutely continuous spectrum (Avila and Jitomirskaya, Commun. Math. Phys. 301 (2011), 563–581).

On the Mean‐Field Limit of Consensus‐Based Methods

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4214-4240, 30 March 2026.
ABSTRACT Consensus‐based optimization (CBO) employs a swarm of particles evolving as a system of stochastic differential equations (SDEs). Recently, it has been adapted to yield a derivative free sampling method referred to as consensus‐based sampling (CBS). In this paper, we investigate the “mean‐field limit” of a class of consensus methods, including

On the Domain of the Pell-Lucas Matrix in the Spaces c and c_0

open access: yesDera Natung Government College Research Journal
In this study, we introduce new Banach sequence spaces $c(\Theta), c_0(\Theta)$, defined via a regular infinite matrix $ \Theta = (\lambda_{nk})$, where \[ \Theta_{nk} = \begin{cases} \dfrac{2\lambda_k}{3\lambda_n+\lambda_{n-1}} & 0 \leq k \leq n ...

Existence of sunny nonexpansive retractions and approximation of fixed points of a representation of nonexpansive mappings

open access: yesNonlinear Analysis
This paper presents an implicit scheme for a representation of nonexpansive mappings on a closed convex subset of a smooth uniformly convex Banach space with respect to a left-regular sequence of means defined on a subset of l∞(S).

On basic sequences in Banach spaces

open access: yes, 1992
Summary: Let \(X\) be a Banach space with \(X^{**}\) separable. If \(X\) has a shrinking basis and \(Y\) is a closed subspace of \(X^{**}\) which contains \(X\), there exists a shrinking basis \((x_ n)\) in \(X\) with two complementary subsequences \((x_{m_ i})\) and \((x_{n_ j})\) so that \([x_{m_ j}]\) is a reflexive space and \(X+ \widetilde {[x_{n_
