Paul McKenney: Automorphisms of P(ω1)/finite

Mathematical logic seminar – January 20, 2015 Time:     12:30 – 13:30 Room:     Wean Hall 8201 Speaker: Paul McKenney Title:     Automorphisms of P(ω1)/finite Abstract: I will discuss some recent work with Paul Larson on automorphisms of the Boolean algebra P(ω1)/finite and related structures, along with some connections to the question of whether it is consistent with ZFC that P(ω)/finite is isomorphic to P(ω1)/finite. continue reading…

Paul McKenney: Forcing axioms and the rigidity of corona algebras III

Mathematical logic seminar – March 19 2013 Time:     12:00 – 13:20 Room:     Wean Hall 7201 Speaker:         Paul McKenney Department of Mathematical Sciences Carnegie Mellon University Title:     Forcing axioms and the rigidity of corona algebras III Abstract:     In the final talk of this series, I will recap some of the discussion from last time and prove one of the results mentioned; namely I will prove that, assuming Todorcevic’s Axiom, every map determined by a coherent family of *-homomorphisms must have a Borel graph. continue reading…
