Borisa Kuzeljevic: A long chain of P-points

Invitation to the Logic Seminar at the National University of Singapore Date: Wednesday, 6 April 2016, 17:00 hrs Room: S17#05-11, Department of Mathematics, NUS Speaker: Borisa Kuzeljevic Title: A long chain of P-points URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html Abstract: We will construct, under CH, a sequence of P-points {U_alpha: alpha < omega_2} in such a way that for every alpha, beta with alpha < beta < omega_2 the ultrafilter U_alpha is Rudin-Keisler reducible to U_beta while the ultrafilter U_beta is not Tukey reducible to U_alpha. continue reading…
