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. |

Recent application of model theory in set theory by Shelah-Malliaris
Juris Steprans circulated some notes on this last year at the Fields Institute. These notes were helpful in that they emphasized the set-theoretic content of the proof and pushed the model theory to the background. Perhaps you can contact him? |

What does ! above = mean
Honestly, this is exactly what I thought when this question bubbled up to the front page! |
