... By a ∆0 formula we mean a formula of set theory in which all the quantifiers appear restricted, that is have one of the forms (∀x ∈ b) or (∃x ∈ b). KP arises from ZF by completely omitting the Power Set Axiom and restricting separation and collection to absolute predicates (cf. [3]), i.e. ∆0 formula ...
