A 3-Scale Haar Wavelet Collocation Method for Numerical Solution of the Nonlinear Gardner Equation

open access: yesMediterranean Journal of Mathematics
Abstract In this paper, a 3-scale Haar wavelet collocation method was applied to the nonlinear Gardner equation which can be used to describe the large-amplitude inner waves in the ocean. We start the solution process with the time discretization of the Gardner equation, with the help of finite difference method.

Reconstructing a rotor from initial and final frames using characteristic multivectors: With applications in orthogonal transformations

open access: yesMathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1218-1235, February 2024.
If an initial frame of vectors {ei}$$ \left\{{e}_i\right\} $$ is related to a final frame of vectors {fi}$$ \left\{{f}_i\right\} $$ by, in geometric algebra (GA) terms, a rotor, or in linear algebra terms, an orthogonal transformation, we often want to find this rotor given the initial and final sets of vectors.

A Novel Efficient Approach for Solving Nonlinear Caputo Fractional Differential Equations

open access: yesAdvances in Mathematical Physics, Volume 2024, Issue 1, 2024.
Several scientific areas utilize fractional nonlinear partial differential equations (PDEs) to model various phenomena, yet most of these equations lack exact solutions (Ex‐Ss). Consequently, techniques for obtaining approximate solutions (App‐S), which sometimes yield Ex‐Ss, are essential for solving these equations.
