Place: Fields Institute (Room 210)

Date: April 22nd , 2016 (13:30-15:00)

Speaker: Juris Steprans

Title: Graph embedding and the P-ideal dichotomy

Abstract: I will discuss a family of proofs of the consistency of a universal graph on $\omega_1$ with the failure of CH that rely on iterating reals and using the P-ideal dichotomy.
