The Poincare Surface of Section projection of the trajectories characterized by given energies in the Henon Heiles potential form a Map in 2-dimensions.
Frocschle (1968) and Henon (1969) were among the first to try to
abstract the features of Henon Heiles potential SOS in and via
an artificial map
in 2-dimensions.
Let and be the variables. The map transforms the (,) plane
into itself. Thus a point
(,) is mapped into (,) via
The skeleton code henon_map.c \begin{rawhtml} implements this map.
Reference: An introduction to Dynamical systems by Arrowsmith and Place has a section on this map.
