Application of a Generalized Secant Method to Nonlinear Equations with Complex Roots

open access: yesAxioms, 2021
The secant method is a very effective numerical procedure used for solving nonlinear equations of the form f(x)=0. In a recent work (A. Sidi, Generalization of the secant method for nonlinear equations. Appl. Math. E-Notes, 8:115–123, 2008), we presented

On the Method of Differential Invariants for Solving Higher Order Ordinary Differential Equations

open access: yesAxioms, 2022
There are many routines developed for solving ordinary differential Equations (ODEs) of different types. In the case of an nth-order ODE that admits an r-parameter Lie group (3≤r≤n), there is a powerful method of Lie symmetry analysis by which the ODE is
