摘要
Given a stationary subset T of omega (1), let (T) over tilde be the set of ordinals in the interval (omega (1) omega (2)) which are necessarily in the image of T by any embedding derived from the nonstationary ideal. We consider the question of the size of (T) over tilde, given T, and use Martin's Maximum and P-max to give some answers.
