On Recurrence Axioms
Abstract
The Recurrence Axiom for a class of \pos\ and a set of parameters is an axiom scheme in the language of ZFC asserting that if a statement with parameters from is forced by a poset in , then there is a ground containing the parameters and satisfying the statement. The tightly super---Laver generic hyperhuge continuum implies the Recurrence Axiom for and . The consistency strength of this assumption can be decided thanks to our main theorems asserting that the minimal ground (bedrock) exists under a tightly -generic hyperhuge cardinal , and that in the bedrock is genuinely hyperhuge, or even super hyperhuge if is a tightly super---Laver generic hyperhuge definable cardinal. The Laver Generic Maximum (LGM), one of the strongest combinations of axioms in our context, integrates practically all known set-theoretic principles and axioms in itself, either as its consequences or as theorems holding in (many) grounds of the universe. For example, double plus version of Martin's Maximum is a consequence of LGM while Cicho\'n's Maximum is a phenomenon in many grounds of the universe under LGM.
