WebbBolzano-Weierstrass Theorem again would result in proving the compactness of the closure set, as needed. As explained above, we begin by proving the following lemma: Lemma. Let Φ be a subset of C(I), the space of continuous real-valued functions on I= [0,1], equipped with the supremum metric. If Φ is totally bounded, then cl(Φ),

WebbThis proof of the compactness theorem is originally due to Gödel. Conversely, for many deductive systems, it is possible to prove the completeness theorem as an effective consequence of the compactness theorem.
