Covering with Chang models
Assume and suppose there are unboundedly many Woodin cardinals and strong cardinals. Let be a limit of Woodin cardinals and strong cardinals such that either is a measurable cardinal or . Covering with Chang Models. There is a transitive model of such that
has a largest cardinal , and for any , defining
and
then, in ,
If in addition there is no inner model with a subcompact cardinal, then
The result gives a covering model with Chang-model-like structural properties from strong large-cardinal hypotheses, while also producing a model of determinacy after the indicated collapse. The supplied text does not state whether this result is intended as a conjecture, theorem, or open problem, so its database status remains open.
