On Existence in Set Theory, Part II: Relative Productivity
Rodrigo Argenton Freire · Notre Dame Journal of Formal Logic · 2014
The present paper continues the investigation initiated in an earlier work. After a short introduction, the notion of relative productivity is defined and a technical apparatus is developed in order to evaluate the classification of the axioms previously obtained. Some results on the semilattice of simple relative degrees are proved at the end of Section 2. Section 3 adds some concluding remarks.
