Problem. Is it consistent with ZFC that $\mathfrak t=\omega_1$ and each $\omega_1$-generated tall $P$-ideal is of the second Baire category?

  • $\begingroup$ I have added (infinite-combinatorics) - feel free to revert the edit if you think the tag does not fit, but to me small uncountable cardinals seem rather close to my understanding of infinitary combinatorics. (I was also considering adding (decriptive-set-theory) but it is probably not ideal fit here. $\endgroup$ – Martin Sleziak Sep 30 '17 at 9:24
