Mathematische Nachrichten, Volume 298, Issue 2, Page 456-477, February 2025.Abstract We give a simple construction of the log‐convex minorant of a sequence {Mα}α∈N0d$\lbrace M_\alpha \rbrace _{\alpha \in \mathbb {N}_0^d}$ and consequently extend to the d$d$‐dimensional case the well‐known formula that relates a log‐convex sequence {Mp}p∈N0$\lbrace M_p\rbrace _{p\in \mathbb {N}_0}$ to its associated function ωM$\omega _M$, that

The Haar System as a Schauder Basis in Spaces of Hardy–Sobolev Type [PDF]
Journal of Fourier Analysis and Applications, 2017 We show that, for suitable enumerations, the multivariate Haar system is a Schauder basis in the classical Sobolev spaces on $\mathbb R^d$ with integrability ...

Viscoelasticity, logarithmic stresses, and tensorial transport equations
Mathematical Methods in the Applied Sciences, Volume 48, Issue 3, Page 2934-2953, February 2025.We introduce models for viscoelastic materials, both solids and fluids, based on logarithmic stresses to capture the elastic contribution to the material response. The matrix logarithm allows to link the measures of strain, that naturally belong to a multiplicative group of linear transformations, to stresses, that are additive elements of a linear ...

The gE-Approximation Property Determined by the Banach Space E = ℓq(ℓp)
MathematicsWe study the gE-approximation property for the Banach space E=ℓq(ℓp), which is an extension of Saphar’s p-approximation property. We establish some characterizations of the gE-approximation property using the space of E-summing operators, which is an ...

An Approach to Solve Fuzzy Fractional Darboux Problems Under the Caputo Derivative
International Journal of Differential Equations, Volume 2025, Issue 1, 2025.This paper investigates the Fuzzy Adomian Decomposition Method to find approximate analytical solutions for linear and nonlinear fuzzy Darboux problems using the Caputo‐type mixed fractional derivative, which plays an important role in applied and engineering sciences. The solutions are formulated as series with easily calculable terms.

Modeling and Analysis of Breast Cancer With Variable‐Order Fractional and Optimal Control Approach
International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.This study presents a novel variable‐order (VO) fractional model (VOFM) to describe breast cancer progression and therapy, incorporating five patient compartments that reflect disease stages and treatment effects, including cardiotoxicity. The model employs the constant proportional Caputo (CPC) VO operator to capture memory effects and time‐varying ...

A Quantitative Version of James’s Reflexivity Theorem
Journal of Function Spaces, Volume 2025, Issue 1, 2025.In this note, we will use a measure of nonreflexivity of Banach spaces, a measure of nonbounded completeness of bases, and a measure of nonshrinkingness of bases to prove a quantitative version of the well‐known reflexivity theorem due to R. C. James.
