WebJul 24, 2024 · My understanding of Gödel's first incompleteness theorem is that no theory that satisfies some finiteness condition can uniquely pin down a model. So I am not really surprised by it. The idea of theories being incomplete -- of not completely pinning down a particular model -- is quite normal. The fact that no theory is complete seems analogous ... Web$\begingroup$ @Raphael: I am very well aware that there is a large conceptual difference between the statements of incompleteness theorem and of the undecidability of the halting problem.

WebMay 2, 2024 · Also, both Godel's and Rosser's proofs apply to any formal system that interprets Robinson's arithmetic, not primitive recursive arithmetic. Soundness is extremely strong, much stronger than ω-consistency. Primitive recursive arithmetic is a (two-sorted) second-order theory, not directly related to the Godel-Rosser incompleteness theorem. WebGödel's incompleteness theorems is the name given to two theorems (true mathematical statements), proved by Kurt Gödel in 1931. They are theorems in mathematical logic . Mathematicians once thought that everything that is true has a mathematical proof. A system that has this property is called complete; one that does not is called incomplete.
