Projective Measure Without Projective Baire, Paperback / softback Book

Projective Measure Without Projective Baire Paperback / softback

Part of the Memoirs of the American Mathematical Society series

Paperback / softback

Description

The authors prove that it is consistent (relative to a Mahlo cardinal) that all projective sets of reals are Lebesgue measurable, but there is a $\Delta^1_3$ set without the Baire property.

The complexity of the set which provides a counterexample to the Baire property is optimal.
