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.

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).

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 ...

Dissociation of J/ψ and Y Using Dissociation Energy Criteria in N‐Dimensional Space
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The analytical exact iteration method (AEIM) has been widely used to calculate N‐dimensional radial Schrodinger equation with medium‐modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasiparticle approach in hot quantum chromodynamics (QCD) medium.

Complementary Lidstone Interpolation and Boundary Value Problems
Journal of Inequalities and Applications, 2009 We shall introduce and construct explicitly the complementary Lidstone interpolating polynomial P2m(t) of degree 2m, which involves interpolating data at the odd-order derivatives. For P2m(t) we will provide explicit representation of the error function,

Thermal Analysis of a Casson Boundary Layer Flow over a Penetrable Stretching Porous Wedge
Journal of Mathematics, Volume 2024, Issue 1, 2024.This work aims to analyze the Casson thermal boundary layer flow over an expanding wedge in a porous medium with convective boundary conditions and ohmic heating. Moreover, the effects of porosity and viscous dissipation are studied in detail and included in the analysis. The importance of this study is due to its applications in biomedical engineering

Investigation of Magnetized Casson Nanofluid Flow along Wedge: Gaussian Process Regression
International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.An unsteady two‐dimensional magnetized Casson nanofluid flow model is constructed over a wedge under the effect of thermal radiation and chemical reaction. The multiple slip effects are also assumed near the surface of the wedge along with the convective boundary restrictions.

Resonance and quasilinear ellipticity [PDF]
Transactions of the American Mathematical Society, 1986 Two resonance-type existence theorems for periodic solutions of second order quasilinear elliptic partial differential equations are established. The first theorem is a best possible result, and the second theorem presents conditions which are both necessary and sufficient.
