<strong>Consequences</strong> <strong>of</strong> <strong>the</strong> <strong>Hahn</strong>-<strong>Banach</strong> <strong>the</strong>orems<br />
Theorem<br />
(The corollary on p. 59) Let X be a locally convex topological<br />
vector space. Then X ∗ separates <strong>the</strong> points <strong>of</strong> X, i.e. when x = y<br />
in X <strong>the</strong>re is a l ∈ X ∗ such that l(x) = l(y).<br />
