Zaslavskii Map

The 2-D map

$\displaystyle x_{n+1}$ $\textstyle =$ $\displaystyle [x_n+\nu(1+\mu y_n)+\epsilon\nu\mu\cos(2\pi x_n)]\quad ({\rm mod\ }1)$  
$\displaystyle y_{n+1}$ $\textstyle =$ $\displaystyle e^{-\Gamma}[y_n+\epsilon\cos(2\pi x_n)],$  


\mu\equiv {1-e^{-\Gamma}\over\Gamma}

(Zaslavskii 1978). It has Correlation Exponent $\nu\approx 1.5$ (Grassberger and Procaccia 1983) and Capacity Dimension 1.39 (Russell et al. 1980).
