WebGödel's First Incompleteness Theorem can be proven as a corollary of the undecidability of the halting problem (e.g. Sipser Ch. 6; blog post by Scott Aaronson). From what I … WebGödel's incompleteness theorem and the undecidability of the halting problem both being negative results about decidability and established by diagonal arguments (and in the 1930's), so they must somehow be two ways to view the same matters. And I thought that Turing used a universal Turing machine to show that the halting problem is unsolvable.

It states that a function on the natural numbers can be calculated by an effective method if and only if it is computable by a Turing machine. The thesis is named after American mathematician Alonzo Church and the British math…

Sets A function, f, is said to be partial recursive if there is a ’-program for it. Theorem 1 There is a total function that is not recursive. Proof: Define f as follows: for every x 2 N, f(x) = ’x(x)+1 if ’x(x) #; 0 if ’x(x)" : It is clear that f is total. We shall prove that there is no ’-program for f.By contradiction,
