In computability theory, the Church–Turing thesis (also known as computability thesis, the Turing–Church thesis, the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a thesis about the nature of computable functions.

WebMar 20, 2015 · The Gödel completeness theorem for first-order logic entails that P is a first-order consequence of a first-order theory T if and only if P can be deduced from T by first-order logic.

WebA Brief Note on Church-Turing Thesis and R.E. 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,
