**linear functional**f separates the subsets M and N of X if and only if it separates the subsets M - N and { 0 } of X. The proof is elementary , and is left to the reader . In dealing with subspaces , it is often convenient to make ...Page 418

If K1 , K , are disjoint closed , convex subsets of a locally convex linear topological space X , and if K , is compact , then some non - zero continuous

If K1 , K , are disjoint closed , convex subsets of a locally convex linear topological space X , and if K , is compact , then some non - zero continuous

**linear functional**on X separates K , and Kz . 12 COROLLARY .Page 421

Let X be a linear space , and let I be a total subspace of X * . Then the

Let X be a linear space , and let I be a total subspace of X * . Then the

**linear functionals**on X which are continuous in the I topology are precisely the functionals in T. The proof of Theorem 9 will be based on the following lemma .### What people are saying - Write a review
