Is the Church-Turing thesis a theorem, conjecture, or axiom?

WebAnswer (1 of 5): It is a conjecture, but an imprecise one. It’s a statement supported by argument, but which lacks an accepted formalism and thus any hope of an immediate mathematical proof.

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. 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… WebBest Public Adjusters in Fawn Creek Township, KS - search by hours, location, and more attributes.

Turing's Fellowship thesis at King's College, Cam bridge, was concerned with the Central Limit Theorem, but he did not publish it because he found that the work had already been done by Feller in 1935.
