Abstract

Applying the seed concept to Prikry tree forcing ℙμ, I investigate how well ℙμ preserves the maximality property of ordinary Prikry forcing and prove that ℙμ, Prikry sequences are maximal exactly when μ admits no non-canonical seeds via a finite iteration. In particular, I conclude that if μ is a strongly normal supercompactness measure, then ℙμ Prikry sequences are maximal, thereby proving, for a large class of measures, a conjecture of W. Hugh Woodin's.
