Higher Classes of Ordinals induced by <_1

Logic 2013-09-25 v1

Abstract

In this article we want to see that it is possible to iterate and generalize the notions presented in "Carlson's <_1-relation on the class of epsilon numbers" such that we can obtain the higher or thinner classes of ordinals induced by the <_1-relation as solutions of conditions. Indeed, these results are so general that in a future article we will be able to characterize the ordinal |Pi_1^1 - CA_0 | as the smallest ordinal of the thinnest class induced by <_1.
