* Local base. A set of open neighbourhoods of a point p of a topological space X is a local base for the topology on X if every open set containing x is a superset of some member of the base.
* Local base. A set B of open neighbourhoods of a point x of a topological space X is a local base at x if every neighbourhood of x contains some member of B.

This is a glossary of some terms used in the branch of mathematics known as topology. See the article on topology for basic definitions.

This glossary is divided into two parts. The first part deals with general concepts, and the second part lists types of topological spaces defined in terms of these concepts. All spaces in this glossary are assumed to be topological spaces.


Part 1 -- topological concepts


Part 2 -- types of topological spaces
