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

Let $A = \set {a, b}$ be a doubleton.

Let $D = \struct {A, \set {\O, A} }$ be the indiscrete space on $A$.

Let $\struct {T \times D, \tau}$ be the product space of $T$ and $D$.

Then $T \times D$ is known as the **double pointed topology** on $T$.
