2015 seminar talk: Measure, category and projective wellorders

Talk held by Vera Fischer (TU Wien) at the KGRC seminar on 2015-01-08.


We will see that every admissible assignment of $\aleph_1$ and $\aleph_2$ to the invariants of measure and category is consistent with the existence of a $\Delta^1_3$ definable wellorder on the reals.
