Determinacy in strong cardinal models
Published online by Cambridge University Press: 12 March 2014
Abstract
We give limits defined in terms of abstract pointclasses of the amount of determinacy available in certain canonical inner models involving strong cardinals. We show for example:
Theorem A. Det(-IND) ⇒ there exists an inner model with a strong cardinal.
Theorem B. Det(AQI) ⇒ there exist type-l mice and hence inner models with proper classes of strong cardinals.
where -IND(AQI) is the pointclass of boldface -inductive (respectively arithmetically quasi-inductive) sets of reals.
