Admissibility and Non-Uniform Dichotomy for Differential Systems
, 2004 The problem of nonuniform exponential dichotomy of linear differential systems in Banach spaces is discussed. It is established a connection between the admissibility of a pair of certain function spaces which are translations invariant, on one hand ...

Banach Spaces of Analytic Vector-valued Functions [PDF]
, 2007 The main theme of the thesis is the study of continuity and approximation problems, involving matrix-valued and vector-valued Hardy spaces on the unit disc ID and its boundary T in the complex plane.

Sequential continuity in the ball topology of a Banach space
, 1999 Consider the isometric property (P): the restriction to the unit ball of every bounded linear functional is sequentially continuous in the ball topology.

On an improved restricted reverse weak‐type bound for the maximal operator
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract We obtain an improved lower bound for the restricted reverse weak‐type estimate of the Hardy–Littlewood maximal operator M$M$. This result is applied to the λ$\lambda$‐median maximal operator mλ$m_{\lambda }$ acting on a Banach function space X$X$.

, 2001 The paper is a survey on recent progress on properties of the Banach space \(c_0\). A sequence space characterization is given for a Banach space to be isometric to a subspace of \(c_0\) and its consequences is investigated. It is shown that \(c_0\) is minimal among sufficiently smooth non-reflexive spaces and maximal among asymptotically flat spaces ...

Kergin approximation in Banach spaces
Journal of Approximation Theory, 2008 We explore the convergence of Kergin interpolation polynomials of holomorphic functions in Banach spaces, which need not be of bounded type. We also investigate a case where the Kergin series diverges.

Stable factorization of the Calderón problem via the Born approximation
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract In this article, we prove the existence of the Born approximation in the context of the radial Calderón problem for Schrödinger operators. The Born approximation naturally appears as the linear component of a factorization of the Calderón problem; we show that the nonlinear part, obtaining the potential from the Born approximation, enjoys ...

A New Proof for a Rolewicz's Type Theorem: An Evolution Semigroup Approach
, 2001 Let $varphi$ be a positive and non-decreasing function defined on the real half-line and $mathcal{U}$ be a strongly continuous and exponentially bounded evolution family of bounded linear operators acting on a Banach space. We prove that if $varphi$ and $

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks
Mathematical Methods in the Applied Sciences, Volume 49, Issue 8, Page 8095-8117, 30 May 2026.ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

Conditions implying the uniqueness of the weak*-topology on certain group algebras [PDF]
, 2009 We investigate possible preduals of the measure algebra M(G) of a locally compact group and the Fourier algebra A(G) of a separable compact group. Both of these algebras are canonically dual spaces and the canonical preduals make the multiplication ...
