Dynamical properties of injective continuous functions on $\mathbb{R}^d$
Thanks! In light of your comment, I added your good point about a stronger downward component and made the wording overall a bit less tentative. |

When is a submanifold of $\mathbf R^n$ given by global equations?
For $S^1$, what about $f(x, y, z) = (x^2 + y^2 - 1, z)$? But is it possible to do a knot? |

Fixed points which are not locally attractive can have distant basins of attraction?
Under one interpretation of your terms, here's an example. The flow defined by $x' = x^2$ has a non-locally-attracting fixed point at 0, but any open set of negative numbers is attracted to it. But perhaps you mean something else? |

Orthogonal foliations
+1. This is really nicely written--it's an excellent example of how to give a helpful expository (as opposed to problem-solving) answer. |

A model of self-organizing behavior
This seems related to the literature on "pulse-coupled oscillators," which is inspired partly by models of synchronized firefly flashing or cricket chirping. It may not treat your exact rule, but if you haven't looked into this already, see for instance: eecs.harvard.edu/~degesys/pulse.html |
