Dual topology

In functional analysis and related areas of mathematics a dual topology is a locally convex topology on a dual pair, two vector spaces with a bilinear form defined on them, so that one vector space becomes the continuous dual of the other space.
The different dual topologies for a given dual pair are characterized by the Mackey–Arens theorem. All locally convex topologies with their continuous dual are trivially a dual pair and the locally convex topology is a dual topology.
Several topological properties depend only on the dual pair and not on the chosen dual topology and thus it is often possible to substitute a complicated dual topology by a simpler one.
==Definition==
Given a dual pair (X, Y, \langle , \rangle), a dual topology on X is a locally convex topology \tau so that
:(X, \tau)' \simeq Y.
Here (X, \tau)' denotes the continuous dual of (X,\tau) and (X, \tau)' \simeq Y means that there is a linear isomorphism
:\Psi : Y \to (X, \tau)',\quad y \mapsto (x \mapsto \langle x, y\rangle).
(If a locally convex topology \tau on X is not a dual topology, then either \Psi is not surjective or it is ill-defined since the linear functional x \mapsto \langle x, y\rangle is not continuous on X for some y.)
