We aim at providing a philosophical analysis of the notion of “proof by Church’s Thesis”, which is – in a nutshell – the conceptual device that permits to rely on informal methods when working in Computability Theory. This notion allows, in most cases, to not specify the background model of computation in which a given ...

Church-Turing Thesis -- from Wolfram MathWorld

WebThe Church-Turing Thesis asserts that all effectively computable numeric functions are recursive and, likewise, they can be computed by a Turing machine, or—more precisely—can be simulated under some representation by a Turing machine. This claim has recently been axiomatized and proven [3, 6]. The Web11] the Extended Church-Turing thesis (ECT) { that any physical system can be e ciently simulated by a Turing machine. However, the validity of the ECT thesis is an asymptotic statement { we cannot make statements about computational complexity other than in the asymptotic limit.

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 … 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. For example, the physical Church–Turing thesis states: "All physically computable functions are Turing-computable." The Church–Turing … See more One can formally define functions that are not computable. A well-known example of such a function is the Busy Beaver function. This function takes an input n and returns the largest number of symbols that a Turing machine with n states can print before halting, … See more One of the important problems for logicians in the 1930s was the Entscheidungsproblem of David Hilbert and Wilhelm Ackermann, … See more Other formalisms (besides recursion, the λ-calculus, and the Turing machine) have been proposed for describing effective calculability/computability. Kleene (1952) adds to the list the functions "reckonable in the system S1" of Kurt Gödel 1936, and Emil Post's … See more Philosophers have interpreted the Church–Turing thesis as having implications for the philosophy of mind.

The meaning of isProof(x, ⌜ψ⌝) is that x is a proof of ψ. Because P is effectively axiomatised, there is such a Turing-decidable predicate. In fact, without loss of generality we can take isProof to be a primitive recursive predicate (using the power of Kleene's T Predicate).

WebSpecifically, I shall argue that the introduction of epistemic constraints have deep implications for the set of computable functions, for the logical and physical Church-Turing thesis—cornerstones of logical and physical computability respectively—might turn out to be false according to which epistemic constraints are accepted. http://www.itk.ilstu.edu/faculty/chungli/mypapers/Church_Turing_RE_note.pdf
