摘要
Unfoldable cardinals are preserved by fast function forcing and the Laver-like preparations that fast functions support. These iterations show, by set-forcing over any model of ZFC, that any given unfoldable cardinal kappa can be made indestructible by the forcing to add any number of Cohen subsets to kappa.
