Suslin tree preservation and club isomorphisms

Logic 2025-04-16 v2

Abstract

We construct a model of set theory in which there exists a Suslin tree and satisfies that any two normal Aronszajn trees, neither of which contains a Suslin subtree, are club isomorphic. We also show that if SS is a free normal Suslin tree, then for any positive integer nn there is a c.c.c. forcing extension in which SS is nn-free but all of its derived trees of dimension greater than nn are special.
