Please give some counterexamples, some definition could be found here. Eventually periodic point and homeomorphism. An eventually periodic point must be an asymptotically periodic point?

1.a recurrent point meanwhile not a transitive point

2.a recurrent point meanwhile not a periodic point

3.a recurrent point meanwhile not a eventually periodic point

I think that a recurrent point is abstract noun, so I need some examples to visualize it in my mind.

    I find your problem statement difficult to follow, and while your other Questions may contain "some definition[s]", it is unreasonable to expect the Reader to go chasing links to find the central definition you want to understand, that of "a recurrent point". Start by giving a definition of that, and it will pave the way to giving "some counterexamples". – hardmath Jun 23 '14 at 04:44

I suspect that you're talking about topological dynamics, where you have a continuous function $T$ from a space $X$ into itself, and using the following definitions:

  1. A "recurrent point" is a point $p$ such that for every neighbourhood $U$ of $p$, there are infinitely many $n$ such that $T^n(p) \in U$.

  2. A "transitive point" is a point $p$ such that for every nonempty open set $A$ there are infinitely many $n$ such that $T^n(p) \in A$.

  3. A "periodic point" is a point $p$ such that for some positive integer $n$, $T^n(p) = p$.

  4. An "eventually periodic point" is a point $p$ such that there exist positive integers $m < n$ such that $T^m(p) = T^n(p)$.

    An example for all your questions is provided by an irrational rotation of a disk. Every point is recurrent, but no points are transitive, and no point except the origin is periodic or eventually periodic.
