Stability of Fredholm properties on interpolation scales

Arkiv för Matematik, 1990
Après avoir mis en évidence une propriété caractérisant les opérateurs de Fredholm, les auteurs montrent que si un opérateur \(T\) linéaire de \(A_ 1+A_ 2\) dans \(B_ 1+B_ 2\) est de Fredholm dans un espace d'interpolation \((A_ 1,A_ 2)_ \theta\) dans \((B_ 1,B_ 2)_ \theta\) (ou intérpolation réelle) alors il reste de Fredholm dans des intérpolés dont ...

Microencapsulated Alkane Wax Melting: Measured by 1H NMR Relaxometry and Diffusometry

Magnetic Resonance in Chemistry, Volume 64, Issue 5, Page 483-493, May 2026.
NMR relaxometry and diffusometry measurements detected greater molecular‐level disordering in microencapsulated n‐alkane waxes versus unencapsulated waxes throughout melting. ABSTRACT Phase change materials (PCMs) are useful for energy storage. Large latent heats make n‐alkane waxes effective PCMs.

Numerical solution of some class of integro-differential equations by using legendre-bernstein basis [PDF]

Journal of Hyperstructures, 2014
In this article, a numerical method is developed to solve the linear integro-differential equations. To this end, it will be divided in two forms, Fredholm integro-differential equations (FIDE) and Volterra integro-differential equations (VIDE). So that,

THE TWO-SIDED ESTIMATES OF THE FREDHOLM RADIUS AND COMPACTNESS CONDITIONS FOR THE OPERATOR ASSOCIATED WITH A SECOND-ORDER DIFFERENTIAL EQUATION

Вестник КазНУ. Серия математика, механика, информатика, 2021
In this paper we consider the properties of the resolvent of a linear operator corresponding to a degenerate singular second-order differential equation with variable coefficients, considered in the Lebesgue space.

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, Volume 183, Issue 10, Page 2578-2591, May 2026.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.

A Nyström Method for 2D Linear Fredholm Integral Equations on Curvilinear Domains

Mathematics, 2023
This paper is devoted to the numerical treatment of two-dimensional Fredholm integral equations, defined on general curvilinear domains of the plane. A Nyström method, based on a suitable Gauss-like cubature formula, recently proposed in the literature ...

Polyfolds: A First and Second Look

, 2016
Polyfold theory was developed by Hofer-Wysocki-Zehnder by finding commonalities in the analytic framework for a variety of geometric elliptic PDEs, in particular moduli spaces of pseudoholomorphic curves.

Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

International Endodontic Journal, Volume 59, Issue 5, Page 873-889, May 2026.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

The Property EA and Local Spectral Theory

International Journal of Mathematics and Mathematical Sciences
In this paper, we introduce and study the spectral property EA. This property means that the difference between the approximate point spectrum and the upper semi-Fredholm spectrum coincides with the difference between the approximate point spectrum and ...

Orientability of Fredholm families and topological degree [PDF]

, 1994
We construct a degree theory for oriented Fredholm mappings of index zero between open subsets of Banach spaces and between Banach manifolds. Our approach is based on the orientation of Fredholm mappings: it does not use Fredholm structures on the domain
