Comb space

In mathematics, particularly topology, a comb space is a particular subspace of

The comb space has properties that serve as a number of counterexamples.

The topologist's sine curve has similar properties to the comb space.

equipped with the subspace topology is known as the comb space.

The comb space and the deleted comb space have some interesting topological properties mostly related to the notion of connectedness.
