Popis: | We investigate forcing properties of perfect tree forcings defined by Prikry to answer a question of Solovay in the late 1960's regarding first failures of distributivity. Given a strictly increasing sequence of regular cardinals $\langle \kappa_n: n< \omega \rangle$, Prikry defined the forcing $\mathbb{P}$ all perfect subtrees of $\prod_{n Comment: 26 pages |
