Church turing theorem

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 … See more J. B. Rosser (1939) addresses the notion of "effective computability" as follows: "Clearly the existence of CC and RC (Church's and Rosser's proofs) presupposes a precise definition of 'effective'. 'Effective … See more Proofs in computability theory often invoke the Church–Turing thesis in an informal way to establish the computability of functions while … See more The success of the Church–Turing thesis prompted variations of the thesis to be proposed.
