2010 seminar talk: Projective wellorders and mad families with big continuum

Talk held by Lyubomyr Zdomskyy (KGRC) at the KGRC seminar on 2010-06-10.


We shall show that b=c=ω_3 is consistent with the existence of a Δ13 denable wellorder of the reals and a Π12 denable ω-mad subfamily of [ω]ω.

This is joint work with Vera Fischer and Sy-David Friedman.
