Abstract:
We continue our study of the class \mathcal{C}(D), where D is a uniform ultrafilter on a cardinal \kappa and \mathcal{C}(D) is the class of all pairs (\theta_1, \theta_2), where (\theta_1, \theta_2) is the cofinality of a cut in J^\kappa/D and J is some (\theta_1 + \theta_2)^+-saturated dense linear order. We show that if (\theta_1, \theta_2) \in \mathcal{C} (D) and D is \aleph_1-complete or \theta_1 + \theta_2 > 2^\kappa, then \theta_1 = \theta_2. - published version (11p)
