Preservation of ultrafilters by Sacks forcing
It might be interesting to see if every hlt-ultrafilter is RK-above a P-point. Andreas Blass may know the answer to such questions! |

Namba forcing and semiproperness
The question of whether SCC implies Namba semiproperness seems interesting, though, and not unreasonable! |

Namba forcing and semiproperness
Philip: I know he shows that the strong Chang conjecture is a consequence of Namba semimproperness in Theorem XII.2.5 of the book. Is SCC actually equivalent? |

regularity of ultrafilters
In the Kanamori-Magidor "Evolution of Large Cardinal Axioms" paper, the question is mentioned as still open. |

Thanks, Andreas! I'll fill in the references as I find them! |

Forcing Notions with Unknown Real/Cardinal Preserving Situations
These notions of forcing aren't going to be of much use for Foreman Maximality as they tend to need instances of GCH to be definable. |

Forcing Notions with Unknown Real/Cardinal Preserving Situations
We get a similar situation for your second question when we look at the problem of "properness for larger cardinals". There, we are trying to iterated forcings that are countably closed, and asking if they preserve cardinals. Roslanowski and Shelah have done a lot of work, but this area of set theory still consists mostly of open problems. |
