- In a 3-D continuous dynamical system the signs of the only possible spectra (of Lyapunov exponents) of an attractor are:
- • (-,-,-) a fixed point
- • (0,-,-) a limit cycle
- • (0,0,-) a 2-torus
- • (+,0,-) a strange attractor
- e.g. Rossler band has spectrum { +0.13 , 0 , -14.1 }
-
- Note: for a continuous system, a non-fixed-point attractor always has 1 zero Lyapunov exponent.
