Minimal bases, ideal extensions, and basic dualities. (English) Zbl 1128.06001

The author introduces the concept of B-spaces (i.e., topological spaces with a smallest base). He investigates the relation of this concept to the concepts of algebraic domains and algebraic posets, provides a universal B-reflection for base spaces (i.e., topological spaces with a prescribed base), a universal B-sobrification, and establishes several equivalences and dualities between certain categories of spaces and categories of ordered sets.
