ARTICLES RELATED TO Topological space - Definition | | | |  Topological space - Definition: Encyclopedia II - Topological space - DefinitionA topological space is a set X together with a collection T of subsets of X satisfying the following axioms:
The empty set and X are in T.
The union of any collection of sets in T is also in T.
The intersection of any pair of sets in T is also in T.
The set T is a topology on X. The sets in T are the open sets, and their complements in X are the closed sets. Th ...

| | | | Topological space - Definition: Encyclopedia II - Topological space - Classification of topological spaces Topological spaces can be broadly classified, up to homeomorphism, by their topological properties. A topological property is a property of spaces that is invariant under homeomorphisms. To prove that two spaces are not homeomorphic it is sufficient to find a topological property which is not shared by them. Examples of such properties include connectedness, compactness, and various separation axioms.

| | | | Topological space - Definition: Encyclopedia II - Topological space - Comparison of topologies A variety of topologies can be placed on a set to form a topological space. When every set in a topology T1 is also in a topology T2, we say that T2 is finer than T1, and T1 is coarser than T2. A proof which relies only on the existence of certain open sets will also hold for any finer topology, and similarly a proof that relies only on certain sets not being open applies to any coarser topology. The terms larger a ...
