Find circle map parameters $K, Omega$, for certain predetermined orbits.












1














Find $K, Omega in mathbb{R}$ such that the circle map $theta_{n-1} = [theta_n + Omega + dfrac{K}{2pi}sin(2pi theta_n)]quad(mod 1)$ has a fixed point and a period $3$ orbit.



I was reading through this document https://www.physics.drexel.edu/~bob/PHYS750_NLD/ch7.pdf to try to get a better understanding of circle maps. And I was wondering if one can find these parameters in some obvious way that I'm just not thinking of?



If somebody has some suggestion as to where I can find the information I need or if somebody could please explain it to me that would be great!



Thanks!
