The long term properties of a system can be obtained by taking the and noticing which vectors approach zero and which approach infinity (in the long run the former will have no effect while the later will attempt to pull the system into an asymptotic approach to themselves (albeit a scaled version of themselves)).
Stability
Dynamical Systems can be divided into two different categories based on their long-term behavior: stable and unstable.
Stable Equilibrium
In the long run, a stable dynamical system asymptotically approaches the zero state () or the original state.
This occurs if the absolute value of all the eigenvalues in are less than (approaches ) or equal to 1 (approaches original or alternates).
Unstable
> 1
Polar
This distinction can be transferred into polar coordinates by the following:
