Bruno, I would like to understand your arguments at a technical level, so I started reading your March 2007 paper. But I got kinda bogged down near the end of Section 2. Could you expand on the paragraph that begins with "Let us define an arithmetical realisation R by a function which assigns to each propositional letter p,q,r... an arithmetical sentence." I understand the general idea which is to create a mapping between propositions and arithmetical sentences R:p->i where i is some arithmetical statement. But where do the propositions come from? Are they the axioms appearing just above plus the theorems that follow from them? Are there no further conditions on R?
You say that G proves A iff PA proves i(A). But doesn't that depend on what map R is chosen? Is this a condition on R? thnx, Brent --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
