Dual spaces of geodesic currents

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Spectral Parameter Power Series for Zakharov‐Shabat Direct and Inverse Scattering Problems

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 14661-14671, 15 November 2025.
ABSTRACT We study the direct and inverse scattering problems for the Zakharov‐Shabat system. Representations for the Jost solutions are obtained in the form of the power series in terms of a transformed spectral parameter. In terms of that parameter, the Jost solutions are convergent power series in the unit disk.

Some Liouville theorems for the p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2002
In this paper we propose a new proof for non-linear Liouville type results concerning the $p$-Laplacian. Our method differs from the one used by Mitidieri and Pohozaev because it uses a comparison principle that can be applied to nondivergence form ...

Nonlinear Sequential Fractional Integro‐Differential Systems: Caputo‐Type Derivatives and Boundary Constraints

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15194-15218, 15 November 2025.
ABSTRACT In recent years, the study of sequential fractional differential equations (SFDEs) has become increasingly important in multiple domains of science and engineering. This work investigates a new class of boundary value problems (BVPs) characterized by nonlocal closed boundary conditions involving SFDEs with Caputo fractional integral operators.

On behavior of solution for delta fractional differences associated with special functions

open access: yesAlexandria Engineering Journal
In this paper, a general idea of Mittag-Leffler function using discrete fractional of delta-type in the Riemann–Liouville sense is initiated. Asymptotic behavior of solutions associated with the Riemann–Liouville fractional difference is proposed herein ...

Quantifying Electron Precipitation Driven by Chorus Waves Using Self‐Consistent Particle‐In‐Cell Simulations

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The precipitation of tens to hundreds of keV electrons from Earth's magnetosphere plays a crucial role in magnetosphere‐ionosphere coupling, primarily driven by chorus wave scattering. Most existing simulations of electron precipitation rely on test particle models that neglect particle feedback on waves.

Extra Zebra Stripes Observed by Macao Science Satellite‐1 in the Inner Radiation Belt

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Zebra stripes, characterized by periodic banded structures in the energy‐L shell spectra of energetic electrons in the Earth's inner radiation belt, are understood to result from the azimuthal drift of electrons perturbed by prompt electric field perturbations.
