On the sigma-compactness of definable Menger spaces
Speaker:
Franklin Tall, University of Toronto
Date and Time:
Friday, December 2, 2016 - 1:30pm to 3:00pm
Location:
Fields Institute, Room 210
Abstract:
In a previous seminar, we saw that an inaccessible sufficed for the consistency of "every projective Menger set of reals is sigma-compact". The inaccessible is in fact necessary.
