# Church-turing thesis

Correctness is this correct as far as i know, the thesis says that all intuitively computable functions can be computed by a turing machine and it is not proven to be true, because of the vague definition of intuitively computable. Church–turing thesisin computability theory, the church–turing thesis (also known as computability thesis,[1] the turing–church thesis,[2] the. Recall that a recursive set is defined as one whose characteristic function is a total recursive function similarly, a decision problem or predicate with domain $latex \mathbb{n}$ is called recursively undecidable or recursively unsolvable iff the corresponding charactersitic function is not a total recursive function. Church–turing thesis topic 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 hypothesis about the nature of computable functions. In computability theory, the church–turing thesis (also known as the turing–church thesis, the church–turing conjecture, church's thesis, church's conjecture, and turing's thesis) is a hypothesis about the nature of computable functions.

No single thesis was ever written, and no joint works by church and turing, rather, the church-turing thesis refers to the acceptance of this idea, that the act of computation can, itself be formalized. You write anyways, the church-turing thesis postulated that turing machines and the lambda calculus could compute the same things not to put too fine a point on it, but this is incorrect.
