Fixed point results for Fractal generation of complex polynomials involving Sine function via Non-standard iterations

Hengxiao Qi, Muhammad Tanveer, Waqas Nazeer, Yu-Ming Chu
2020 IEEE Access  
This paper demonstrates some fixed point results for a sine function (i.e. sin(z n ) + c) via non-standard iterations (i.e. Mann, Ishikawa and Noor iterations etc.).  ...  Noor, CR and SP iterations) have same escape radii for any complex polynomial, so we use these results for S, CR and SP iterations also to apply for the generation of Julia and Mandelbrot sets with sin  ...  :Fixed point results for Fractal generation of complex polynomials involving Sine function via Non-standard iterations This work is licensed under a Creative Commons Attribution 4.0 License.  ...

Asymmetric collapse by dissolution or melting in a uniform flow

Chris H. Rycroft, Martin Z. Bazant
2016 Proceedings of the Royal Society A  
The structure of the non-analytic function is examined for three different test cases, and a practical approach to determine the collapse point using a generalized Newton--Raphson root-finding algorithm  ...  The simulations reveal a surprising exact relationship whereby the collapse point is the root of a non-analytic function given in terms of the flow velocity and the Laurent series coefficients describing  ...  As is typical for Newton-Raphson iterations of complex functions, the plot has a fractal structure, with large basins of attraction surrounding each root.  ...
