He could have easily2 come up with an independence result for PA as Gentzen’s proof only utilizes primitive recursive sequences of ordinals and the equivalent theorem about primitive recursive Goodstein sequences is expressible in the language of PA (see Theorem 2.8).

WebDefinition 2.1. Goodstein [ 7] defined operations mediating between ordinals <\varepsilon _ {0} and natural numbers. For naturals m > 0 and c ≥ b ≥ 2 let S c b ( m) be the integer resulting from m by replacing the base b in the complete b … WebBut Goodstein's theorem holds in the standard model, as Goodstein proved. A second point is that you may find that there are no specific "natural" models of PA at all other than the standard model. For example, Tennenbaum proved that there are no computable nonstandard models of PA; that is, one cannot exhibit a nonstandard model of PA so ... boucherie robertville
