Rathjen, M (2013) Relativized ordinal analysis: The case of Power Kripke-Platek set theory. Annals of Pure and Applied Logic. ISSN 0168-0072
Abstract
The paper relativizes the method of ordinal analysis developed for Kripke-Platek set theory to theories which have the power set axiom. We show that it is possible to use this technique to extract information about Power Kripke-Platek set theory, KP (P). As an application it is shown that whenever KP (P) + AC proves a Π statement then it holds true in the segment V of the von Neumann hierarchy, where τ stands for the Bachmann-Howard ordinal.
