Abstract:We show that under ZF + DC, even if every set of reals is measurable, not necessarily every set of reals has the Baire property. This was somewhat surprising, as for the Σ 2 1 set the implication holds. This research was partially supported by an NSF grant and the U.S.-Israel Binational Science Foundation.
