Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Numerical Treatment of Fixed Point Applied to the Nonlinear Fredholm Integral Equation

, 2009
The authors present a method of numerical approximation of the fixed point of an operator, specifically the integral one associated with a nonlinear Fredholm integral equation, that uses strongly the properties of a classical Schauder basis in the Banach

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.

Fredholm-Choquet integral equations

Journal of Integral Equations and Applications, 2019
The author considers the classical second-kind Fredholm integral equation, in which the Lebesgue-type integral \(\int\) is replaced by the more general Choquet integral \((\mathrm{c}) \int\) with respect to a monotone, submodular and continuous from below set function \(\mu: \mathcal{C}\rightarrow [0,+\infty]\), and studies the corresponding Fredholm ...

A note on dual integral equations involving inverse associated Weber-Orr transforms

International Journal of Mathematics and Mathematical Sciences, 1996
We consider dual integral equations involving inverse associated Weber-Orr transforms. Elementary methods have been used to reduce dual integral equations to a Fredholm integral equation of second kind. Some known results are obtained as special case.
