Hyperbolic point page contribution
Hi, I'm watching the Hyperbolic point and you've contributed with somethings that I agree.

However, you've erased:

"" Notice that these properties are quite strong on a dynamical system: structurally stable for instance rules out some important phenomena generally associated with chaos. Unfortunately, most of the dynamical systems that occur on practical situations have non-hyperbolic fixed points. ""

They are not questionable, since you can find them in the book it is cited, page 129. That's why the citation is there... Jorgecarleitao (talk) 16:41, 25 November 2011 (UTC)


 * I'm going to move this to the discussion page for Hyperbolic point. I removed that paragraph based on clarity, not accuracy.  The first sentence is vague and doesn't make any sense where it appeared in the article.  What are the important phenomena generally associated with chaos?  If you can add this detail, then I think it would be very helpful to have in the article.  The second sentence is garbage.  There is no measure on "dynamical systems that occur in practical situations" and so there's no way to talk about a property that "most" of them have.  I'll take a look at Ott and see if I can't make some of these ideas precise.  bradweir (talk) 18:16, 25 November 2011 (UTC)
