Choiceless cardinals and the continuum problem

Logic 2022-01-28 v1

Abstract

Under large cardinal hypotheses beyond the Kunen inconsistency -- hypotheses so strong as to contradict the Axiom of Choice -- we solve several variants of the generalized continuum problem and identify structural features of the levels VαV_\alpha of the cumulative hierarchy of sets that are eventually periodic, alternating according to the parity of the ordinal α\alpha. For example, if there is an elementary embedding from the universe of sets to itself, then for sufficiently large ordinals α\alpha, the supremum of the lengths of all wellfounded relations on VαV_\alpha is a strong limit cardinal if and only if α\alpha is odd.
