Title: Around a question of Juhasz

Abstract: We’ll investigate some results related to a question of Juhasz. We’ll show that consistently, there is no real valued measurable cardinal below the continuum and there is a finitely additive extension of Lebesgue measure whose null ideal is a sigma ideal. We also show that there is a countable partition of

reals into interior free sets under the density topology of any such extension. Joint work with Kunen.
