Stability range of parameters at fixed points for a class of complex dynamics

Zhen-Hua Feng, Hai-Bo Sang, B. S. Xie

We study the parameters range for the fixed point of a class of complex dynamics with the rational fractional function as $R_{n,a,c}(z)=z^n+\frac{a}{z^n}+c$, where $n=1,2,3,4$ is s…
