We say a point x is a limit point of the set A if every open set containing x has a point of A that is not x. For example, every point of [0,1] is a limit point of (0,1) in the usual topology of R.

First of all, I hope you're in a Hausdorff space or this question is moot. If you are, then there are a few definitions I've seen before to answer this question:
A point p in X is a limit point of X if the intersection of any region (or neighborhood, ball of radius epsilon, etc) containing p and the topological space X (excluding p) is non-empty. The interval answer given above is a good example of this.
Second, you can say that p in X is a limit point if it is the limit of an infinite, convergent sequence of points in X.

Boy, I'm really reaching my limit now.

Are you talking about the homotopic limit problem for two-primary
Algebraic K (that K should be a forward slant) theory?

Go to ScienceDirect.com, or just key in topology. This is a
really twisted site you know.

Un point est dit point limite en topologie si n'importe kel de son voisinage contient un autre point different de lui. Soit a le point, alors V k> 0, il exist b tel que /b-a/ Comprendo???
