In mathematics, specifically in order theory and functional analysis, an ordered vector space X {\displaystyle X} {\displaystyle X} is said to be regularly ordered and its order is called regular if X {\displaystyle X} {\displaystyle X} is Archimedean ordered and the order dual of X {\displaystyle X} {\displaystyle X} distinguishes points in X {\displaystyle X} {\displaystyle X}.[1] Being a regularly ordered vector space is an important property in the theory of topological vector lattices.

Examples

[edit ]

Every ordered locally convex space is regularly ordered.[2] The canonical orderings of subspaces, products, and direct sums of regularly ordered vector spaces are again regularly ordered.[2]

Properties

[edit ]

If X {\displaystyle X} {\displaystyle X} is a regularly ordered vector lattice then the order topology on X {\displaystyle X} {\displaystyle X} is the finest topology on X {\displaystyle X} {\displaystyle X} making X {\displaystyle X} {\displaystyle X} into a locally convex topological vector lattice.[3]
