Webin which the axioms have been investigated, but the upshot is that mathematicians are very con dent that the standard axioms (called ZFC), combined with the rules of logic, do not lead to errors. Mathematicians are unlikely to accept more axioms; we do not need more axioms, and we are con dent about the ones we have. A8 Axiom of the Power set. WebZFC+ A1 proves that ZFC+ A2 is consistent; or ZFC+ A2 proves that ZFC+ A1 is consistent. These are mutually exclusive, unless one of the theories in question is actually inconsistent. In case 1, we say that A1 and A2 are equiconsistent. In case 2, we say that A1 is consistency-wise stronger than A2 (vice versa for case 3). WebThe Axioms of Set Theory ZFC In this chapter, we shall present and discuss the axioms of Zermelo-Fraenkel Set Theory including the Axiom of Choice, denoted ZFC.
