Definition:Particular Point Topology/Finite

Definition
Let $S$ be a set which is non-empty.

Let $p \in S$ be some particular point of $S$.

Let $T = \left({S, \tau_p}\right)$ be the particular point space on $S$ by $p$.

Let $S$ be finite.

Then $\tau_p$ is a finite particular point topology, and $\left({S, \tau_p}\right)$ is a finite particular point space.
