There may be infinitely many near-coherence classes under u < ∂

  • Heike Mildenberger (a1)

Abstract

We show that in the models of u < ∂ from [14] there are infinitely many near-coherence classes of ultrafilters, thus answering Banakh's and Blass' Question 30 of [3] negatively. By an unpublished result of Canjar, there are at least two classes in these models.
