The 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 ...

Let X be a linear space , and let T be a total subspace of X * . Then the linear functionals on X which are continuous in the I topology are precisely the functionals in l . The proof of Theorem 9 will be based on the following lemma .
