English: The figure shows two orbits on xy-phase plane of the following delayed logistic map

${\displaystyle {\begin{cases}x_{n+1}=y_{n}\\y_{n+1}=ay_{n}(1-x_{n})\end{cases}}}$.

The parameter of the right figure is a = 1.95 and one of the left figure is 2.05, but both initial conditions are the same x₀ = 0.6 and y₀ = 0.6. A Neimark-Sacker bifurcation occurs at a = 2. Once the bifurcation occurs, the attractor changes from a fixed point to a closed curve (quasi-periodic orbit).
