Abstract
We answer a question of Woodin by showing that assuming an inaccessible cardinal which is a limit of -supercompact cardinals exists, there is a stationary set preserving forcing so that . We also introduce a new forcing axiom , show it is consistent assuming a supercompact limit of supercompact cardinals and prove that it implies . Consequently, implies `` is -dense".
