WebThe Hénon map is a discrete-time dynamical system. It is one of the most studied examples of dynamical systems that exhibit chaotic behavior. The Hénon map takes a point ( x n, y n) in the plane and maps it to a new point. { x n + 1 = 1 − a x n 2 + y n y n + 1 = b x n. import brainpy as bp import brainpy.math as bm import matplotlib.pyplot ...
