The generalized derived model theorem for regularity of Θ
The generalized derived model theorem for regularity of Θ
Let be a Woodin cardinal that is a limit of Woodin cardinals. Let be -generic for , and let be the derived model at computed in . Let denote the club filter on . Generalized derived model conjecture. In , both
and
This would extend the known derived model results for and supercompactness of to stronger regularity of ; the paper explains that the corresponding stronger determinacy assumptions were not known to be consistent from large cardinals.
