Many forcing axioms for all regular uncountable cardinals

arXiv:2107.05755

Abstract

A central theme in set theory is to find universes with extreme, well-understood behaviour. The case we are interested in is assuming GCH and has a strong forcing axiom of higher order than usual. Instead of "for every suitable forcing notion for~" we shall say "for every such family of forcing notions, depending on stationary , for some such stationary set we have\dots". Such notions of forcing are important for Abelian group theory, but this application is delayed for a sequel.
