Definition talk:Stability (Differential Equations)

This page references a lot of terms which need definitions, and links to them.

I also believe that:
 * $$||x - x_0|| < \delta \Rightarrow ||\phi(t,x) - \phi(t,x_0)|| < \epsilon$$

should perhaps be rendered:
 * $$|x - x_0| < \delta \Rightarrow |\phi(t,x) - \phi(t,x_0)| < \epsilon$$

i.e. the notation defining "absolute value" not "norm" - if it's the latter then I don't understand what it means and it needs to be explained. --Matt Westwood 20:40, 20 April 2010 (UTC)
