PFA conjecture on derived models at limits of Woodin cardinals
Let denote the derived model at , let be its supremum of ordinals surjected by its reals, and let be the successor cardinal of . Suppose is a limit of Woodin cardinals. PFA conjecture. The following both hold:
This conjecture asks how a global forcing axiom such as PFA constrains the new derived model at a limit of Woodin cardinals. It concerns both the size of the derived model's and whether it satisfies determinacy for games on reals; the supplied context gives no resolution status.
