Proof of <strong>Baire</strong>’s <strong>category</strong> <strong>theorem</strong> - continued<br />

Next we find an open set B2 such that<br />

B2 ⊆ V2 ∩ B1<br />

such that d(y,x) ≤ 1<br />

2 when S is complete metric space and such<br />

that B2 is compact when S is a locally compact Hausdorff space.<br />

This is done as above: Since V2 is dense, V2 ∩ B1 is not empty.<br />

Repeat then the previous arguments.<br />
