Godel's theorem for dummies
Webboth ThT and RefT are c.e. by Theorem 6., i.e., both ThT and its complement are c.e., so ThT is computable. Now we can give the rst (in a sense the most direct) proof of the incom-pleteness theorem. 9. G odel’s First Incompleteness Theorem. If T is a computably axioma-tized, consistent extension of N, then T is undecidable and hence incomplete. WebWhat is the difference between Gödel's completeness and incompleteness theorems?
