Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations

Annalen der Physik, Volume 537, Issue 6, June 2025.
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Unveiling What Makes Saturn Ring: Quantifying the Amplitudes of Saturn's Planetary Normal‐Mode Oscillations and Trends in C‐Ring Properties Using Kronoseismology (VII)

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Certain spiral density waves in Saturn's rings are generated through resonances with planetary normal modes, making them valuable probes of Saturn's internal structure. Previous research has primarily focused on the rotation rates of these waves. However, other characteristics of these waves also contain valuable information about the planet's

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.

Reconstruction of an initial function from the solutions of the fractional wave equation on the light cone trace

Mathematical Methods in the Applied Sciences, Volume 47, Issue 12, Page 9469-9475, August 2024.
We reconstruct the initial functions from the trace of the solution of an initial value problem for the wave equation on the light cone. A method to recover the initial function from the solution of the wave equation on the light cone is already known for odd spatial dimensions.

Maximum principle for the weak solutions of the Cauchy problem for the fourth‐order hyperbolic equations

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 1, June 2024.
Abstract We investigate the maximum principle for the weak solutions to the Cauchy problem for the hyperbolic fourth‐order linear equations with constant complex coefficients in the plane bounded domain.

Totally deranged elements of almost simple groups and invariable generating sets

Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.
Abstract By a classical theorem of Jordan, every faithful transitive action of a non‐trivial finite group has a derangement (an element with no fixed points). The existence of derangements with additional properties has attracted much attention, especially for faithful primitive actions of almost simple groups.

Minimal surfaces with symmetries

Proceedings of the London Mathematical Society, Volume 128, Issue 3, March 2024.
Abstract Let G$G$ be a finite group acting on a connected open Riemann surface X$X$ by holomorphic automorphisms and acting on a Euclidean space Rn$\mathbb {R}^n$ (n⩾3)$(n\geqslant 3)$ by orthogonal transformations. We identify a necessary and sufficient condition for the existence of a G$G$‐equivariant conformal minimal immersion F:X→Rn$F:X\rightarrow

A nonlocal problem for fourth order hyperbolic equations with multiple characteristic

Electronic Journal of Differential Equations, 2002
In this paper, we study fourth order differential equations with multiple characteristics and dominated low terms. We prove the existence and uniqueness of a Riemann function for this equation, and then provide an integral representation of the general ...
