In functional analysis and related areas of mathematics a Brauner space is a complete compactly generated locally convex space having a sequence of compact sets such that every other compact set is contained in some .
Brauner spaces are named after Kalman George Brauner, who began their study.[1] All Brauner spaces are stereotype and are in the stereotype duality relations with Fréchet spaces:[2][3]
Special cases of Brauner spaces are Smith spaces.
In the special case when possesses a structure of a topological group the spaces , , become natural examples of stereotype group algebras.
