Church: a precisely stated problem without an effective general solution

Church connected effective calculation with formal notions of definability and established an undecidability result in elementary number theory. This helped turn the limits of computation into mathematical questions with explicit definitions.

What is recorded here?

Church connected effective calculation with formal notions of definability and established an undecidability result in elementary number theory. This helped turn the limits of computation into mathematical questions with explicit definitions.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

The formal undecidability theorem is distinct from the Church–Turing thesis identifying informal effective computation with a formal model. This source is a separate contribution from Turing’s machine-based work, not a second count of that paper.
