WebStrict Formalism. Church's Thesis is nowadays generally accepted, but it can be argued that it does not even "make sense", on the grounds that mathematics cannot be allowed to deal with informal concepts of any kind..

WebA Simple Example. Here's an example of a simple lambda expression that defines the "plus one" function: λx.x+1 (Note that this example does not illustrate the pure lambda calculus, because it uses the + operator, which is not part of the pure lambda calculus; however, this example is easier to understand than a pure lambda calculus example.). This example … WebAnswer (1 of 3): The Church-Turing thesis is not a mathematical theorem but a philosophical claim about the expressive power of mathematical models of computation.

WebChurch's Theorem states: For suitable L, there exists no effective method of deciding which propositions of L are provable. The statement is proved by Church (I, last paragraph) with the special assumption of w-consistency, and by Rosser (IV, Thm. III) with the special assumption of simple consistency.

This was done by Alonzo Church in 1935 with the concept of "effective calculability" based on his λ-calculus, and by Alan Turing the next year with his concept of Turing machines.
