An Analytical Study on Two High-Order Hybrid Methods to Solve Systems of Nonlinear Equations

open access: yesJournal of Mathematics, 2023
In order to solve systems of nonlinear equations, two novel iterative methods are presented. The successive over-relaxation method and the Chebyshev-like iterative methods to solve systems of nonlinear equations have combined to obtain the new algorithms.

Rational Approximation Method for Stiff Initial Value Problems

open access: yesMathematics, 2021
While purely numerical methods for solving ordinary differential equations (ODE), e.g., Runge–Kutta methods, are easy to implement, solvers that utilize analytical derivations of the right-hand side of the ODE, such as the Taylor series method ...

Finite element multistep multideriavative schemes for parabolic equations [PDF]

open access: yes, 1976
The linear, homogeneous, parabolic equation is solved by applying finite element discretizations in space and A0 —stable, linear multistep, multiderivative (L.M.S.D.) methods in time. Such schemes are unconditionally stable. An error analysis establishes
