Regularly ordered explained
is said to be
regularly ordered and its order is called
regular if
is
Archimedean ordered and the
order dual of
distinguishes points in
. Being a regularly ordered vector space is an important property in the theory of
topological vector lattices.
Examples
Every ordered locally convex space is regularly ordered. The canonical orderings of subspaces, products, and direct sums of regularly ordered vector spaces are again regularly ordered.
Properties
If
is a regularly ordered
vector lattice then the
order topology on
is the finest topology on
making
into a locally convex
topological vector lattice.
