Constructing generics over ultrapowers by extenders
Ben-Shalom modified Woodin's proof for the consistency of GCH failing at a measurable cardinal. We will extend the result, getting failures of GCH with bigger gaps. The proof requires new techniques involving a square sequence
and PCF theoretical arguments.
