On the Question of Absolute Undecidability? Peter Koellner The incompleteness theorems draw in that for every su ciently strong consistent formal system of math in that location be numerical statements undecided carnal knowledge to the system.1 A natural and intriguing question is whether there are mathematical statements that are in some sense abruptly undecidable, that is, undecidable relative to any set of axioms that are justi?ed. G¨del was contiguous to pip out that his original incompleteness theorems did o not stand up instances of absolute undecidability and hence did not countercheck Hilberts sentence that for every precisely formulated mathematical question there is a de?nite and discoverable answer. However, in his sequent work in set theory, G¨del uncovered what he initially regarded as a o plausible chance for an absolutely undecidable statement. Furthermore, he expressed the hope that one efficacy actually prove this. Eventually he came to reject this interpret and, moving to the former(a) extreme, expressed the I am indebted to hindquarters sword and Hugh Woodin for introducing me to the subject and sharing their insights into G¨dels program.
