Definition:Limit Point/Topology

Definition
Let $T = \struct {S, \tau}$ be a topological space.

Limit Point of Point
The concept of a limit point can be sharpened to apply to individual points, as follows:

Examples

 * Every point of $\R$ is a limit point of $\R$ in the usual (Euclidean) topology.


 * The set $\Z$ has no limit points in the usual (Euclidean) topology of $\R$.
