In topology and related branches of mathematics, **separated sets** are pairs of subsets of a given topological space that are related to each other in a certain way. The notion of when two sets are separated or not is important both to the notion of connected spaces (and their connected components) as well as to the separation axioms for topological spaces.

Separated sets should not be confused with separated spaces (defined below), which are somewhat related but different. Separable spaces are again a completely different topological concept.

### Famous quotes containing the words sets and/or separated:

“bars of that strange speech

In which each sound *sets* out to seek each other,

Murders its own father, marries its own mother,

And ends as one grand transcendental vowel.”

—Randall Jarrell (1914–1965)

“Substances at base divided

In their summits are united;

There the holy essence rolls,

One through *separated* souls.”

—Ralph Waldo Emerson (1803–1882)
