# Indiscrete Space is Ultraconnected

Jump to navigation Jump to search

## Theorem

Let $T = \struct {S, \set {\O, S} }$ be an indiscrete topological space.

Then $T$ is ultraconnected.

## Proof

There is only one non-empty closed set in $T$.

So there can be no two closed sets in $T$ which are disjoint.

Hence (trivially) $T$ is ultraconnected.
