Projective measure without projective Baire
Abstract
We prove that it is consistent (relative to a Mahlo cardinal) that all projective sets of reals are Lebesgue measurable, but there is a 13 set without the Baire property. The complexity of the set which provides a counterexample to the Baire property is optimal.
