Irreversibility analysis of the flow of a radiative Casson–Williamson hybrid ferrofluid over a moving cylinder

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 3, March 2025.
Abstract Entropy generation refers to the energy losses and irreversibilities in the dynamics of non‐linear flow and heat transfer process. Its applications span a wide range, including heat exchangers, turbomachinery, chemical reactors, microfluidic devices, and many others.

Variation of parameters and initial time difference Lipschitz stability of impulsive differential equations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 3, Page 3496-3508, February 2025.
In this paper, we investigate the Lipschitz stability of a perturbed impulsive differential system concerning the unperturbed system. We employ the variation of parameters or the constant of variation for impulsive differential systems with an initial time difference.

Spectral Optimized Multiderivative Hybrid Block Method for Fitzhugh–Nagumo Equations

International Journal of Differential Equations, Volume 2025, Issue 1, 2025.
The Fitzhugh–Nagumo equation, a key model for excitable systems in biology and neuroscience, requires efficient numerical methods due to its nonlinear nature. A spectral optimized multiderivative hybrid block method is proposed, constructed using a multistep collocation and interpolation technique with an approximated power series as the basis function.

Analytic calculation of energies and wave functions of the quartic and pure quartic oscillators

, 2006
Ground state energies and wave functions of quartic and pure quartic oscillators are calculated by first casting the Schr\"{o}dinger equation into a nonlinear Riccati form and then solving that nonlinear equation analytically in the first iteration of ...

Novel Technique for Solving Fractional‐Order Rabies Model With Computational Simulations

International Journal of Differential Equations, Volume 2025, Issue 1, 2025.
Mathematical modeling using noninteger‐order derivatives has gained rapid attention among scientists and researchers in recent years. This manuscript investigates the dynamics of rabies transmission in a predator–prey framework by formulating the problem as a system of nonlinear fractional initial value problems (FIVPs).
