摘要
The Wholeness Axiom (WA) is an axiom schema that can be added to the axioms of ZFC in an extended language {epsilon,j}, and that asserts the existence of a nontrivial elementary embedding j : V --> V. The well-known inconsistency proofs are avoided by omitting from the schema all instances of Replacement for j-formulas. We show that the theory ZFC + V = HOD + WA is consistent relative to the existence of an I-1 embedding. This answers a question about the existence of Laver sequences for regular classes of set embeddings: Assuming there is an I-1-embedding, there is a transitive model of ZFC + WA+ "there is a regular class of embeddings that admits no Laver sequence."
