Paint by number: Uncovering phase flows of an integrable dynamical system
Liam M. Healy, Étienne Deprit · Computers in Physics · 1991
Given an integrable dynamical system with one degree of freedom, ‘‘painting’’ the integral over phase space proves to be a powerful technique for uncovering both global and local behavior.This graphical technique avoids numerical integration, employing instead a nonlinear method of assigning contrasting colors to the energy values to distinguish subtle details of the flow.
