Talk:Center manifold

Not enough
I hope the new information is helpful enough. (FredTschanz 11:25, 29 June 2007 (UTC))

 * I removed the technical tag and added appropriate tags. The problem isn't that the article is technical; it's that the article is written crappily.  There's a distinction.  --C S (talk) 06:12, 19 February 2009 (UTC)

Bouncing ball example
I cannot figure out what the bouncing ball example is saying. I don't believe its describing the center manifold. Its not even clear what the manifold is... 67.198.37.16 (talk) 04:23, 25 September 2020 (UTC)


 * I removed it. The canonical example is Saturn's rings. Tidal forces exert the usual stretch-and-shrink mean that particles above the ring oscillate up and down (the ring thus looks like is attractive); particles in the ring have a random walk in the radius (as they gravitionally interact with other particles in the ring, exchanging energy with them during close encounters). The unstable manifold is the hyperbolic orbits. 67.198.37.16 (talk) 04:34, 25 September 2020 (UTC)
