WebOct 10, 2016 · Gödel first incompleteness theorem states that certain formal systems cannot be both consistent and complete at the same time. One could think this is easy to prove, by giving an example of a self-referential statement, for instance: "I am not provable". But the original proof is much more complicated: WebFirst, in Godel's theorem, you are always talking about an axiomatic system S. This is a logical system in which you can prove theorems by a computer program, you should think of Peano Arithmetic, or ZFC, or any other first order theory with a computable axiom schema (axioms that can be listed by a fixed computer program).
WebSimilarly, Gödel's Completeness Theorem tells us that any valid formula in first order logic has a proof, but Trakhtenbrot's Theorem tells us that, over finite models, the validity of first order formulae is undecideable. So finite proofs don't necessarily correspond to computable operations.
