Application of Fixed Point Iterations in Generation of Fractals for Higher-Order Complex Polynomial
摘要
We develop the escape criterion for higher-order complex-valued polynomials \(f(z)=z^n+az^2+bz+c\) via three-step Noor iteration endowed with s-convexity. From this, we deduce the escape criterion for the same polynomial using Ishikawa and Mann iterations endowed with s-convexity. We use our results to explore mutants of the classical Mandelbrot as well as Julia sets in Noor, Ishikawa and Mann orbits endowed with s-convexity and observe certain patterns in these distinct orbits. It is interesting that most of the visualized fractals have a ring in the center and are similar to beautiful natural objects.
