我们证明了某类半真迭代的成员不加可数序数集。因此,从合适的大基数开始,可以得到一个模型,其中连续统假设成立,并且从ω1到ω1的每个函数都被一个序数小于ω2的标准函数限制在俱乐部上。
We show that the members of a certain class of semi-proper iterations do not add countable sets of ordinals. As a result, starting from suitable large cardinals one can obtain a model in which the Continuum Hypothesis holds and every function from ω1 to ω1 is bounded on a club by a canonical function for an ordinal less than ω2.
