James Cummings: Forcing Pi_2 statements II
Mathematical logic seminar – September 22, 2015
Time: 12:30 – 13:30
Room: Wean Hall 7201
Speaker: James Cummings
Department of Mathematical Sciences
CMU
Title: Forcing Pi_2 statements II
Abstract:
We often find ourselves needing to force assertions of the general form “for every x there exists y….” where typically x and y are subsets of some regular cardinal κ
We will consider three general cases (of increasing difficulty)
κ is ω1
κ is the successor of an uncountable regular cardinal
κ is the successor of a singular cardinal continue reading…
