High-Dimensional Chaotic Lorenz System: Numerical Treatment Using Changhee Polynomials of the Appell Type

Presenting and simulating the numerical treatment of nine-dimensional fractional chaotic Lorenz system is goal this work. The spectral collocation method (SCM), which makes use Changhee polynomials Appell type, suggested approximation technique to achieve goal. A rough formula for Caputo derivative first derived, it used build strategy model’s solution. This procedure creates a algebraic equations from model that was provided. We validate effectiveness precision provided approach by evaluating residual error function (REF). compare results obtained with fourth-order Runge–Kutta other existing published outcomes demonstrate simple effective tool such models.
