Abundance of strange attractors

In 1976 [He] H~non performed a numerical study of the family of diffeomorphisms of the plane ha,b(X, y)=(1-ax2+y, bx) and detected for parameter values a=l.4, b=0.3, what seemed to be a non-trivial attractor with a highly intricate geometric structure. This family has since then been the subject of ... View More
