Abstract. We reprove Gitik’s theorem that if the GCH holds and o(κ) = κ + 1 then there is a generic extension in which κ is still measurable and there is a closed unbounded subset C of κ such...

The covering lemma up to a Woodin cardinal (1997)

Mitchell, William J., Schimmerling, Ernest, Steel, John R.

A cardinal kappa is countably closed if mu^omega < kappa whenever mu < kappa. Assume that there is no inner model with a Woodin cardinal and that every set has a sharp. Let K be the core model....
