An Example of Three-Dimensional Chaos
This Demonstration illustrates the periodic or chaotic behavior and the sensitivity to initial conditions of three-dimensional maps of the form:[more]
x'(t)=f(x(t),y(t),z(t)) y'(t)=g(x(t),y(t),z(t)) z'(t)=h(x(t),y(t),z(t))
The functions , , and here are nonlinear differential equations with three parameters , , and . For a particular selection of these, you can observe periodic behavior, period doubling, or chaotic behavior. Both the Rössler (map 4) and Lorentz (map 5) systems can be considered as special cases. Try your own set of equations by changing the functions in the program.[less]
The systems considered here are as follows:
map 3 (Rössler):
map 5 (Lorentz):
