Computation of bifurcation fractals for 2D symplectic mappings

Watch supplementary videos on YouTube

For a quadratic mapping:

$$ \begin{aligned} & q \to p \\ & p \to -q + w p + p^2 \end{aligned} $$

two symmetry lines, $p=q$ and $p=1/2(w q + q^2)$ cover full 2D plane. Fractals bellow are computed in $(w, q)$ space with $w$ in [-3.00, 2.00] and $q$ in [-1.25, 1.75] using the second symmetry line. Color corresponds to different indicators.

  • Frequency & mode locking (tongues)
