Web20 de fev. de 2024 · The core idea of this incompleteness theorem is best described by the simple sentence “ I am not provable ”. Here, two options are possible: a) the sentence is right - and therefore it is not provable; or b) the sentence is false, and it is provable - in which case the sentence itself is false. Webof all the incompleteness proofs discussed as well as the role of ω-inconsistency in Gödel’s proof. 2.
