Abstract

A club consisting of former regulars is added to an inaccessible cardinal, without changing cofinalities outside it. The initial assumption is optimal. A variation of the Radin forcing without a top measurable cardinal is introduced for this.

另一种添加前正则的封闭无界集合的方法

一个由以前的常客组成的俱乐部被添加到一个无法接近的枢机主教，而不改变它之外的合意。初始假设是最优的。为此介绍了一种没有顶部可测基数的Radin强迫的变化。

期刊介绍： The journal publishes research papers and occasionally surveys or expositions on mathematical logic. Contributions are also welcomed from other related areas, such as theoretical computer science or philosophy, as long as the methods of mathematical logic play a significant role. The journal therefore addresses logicians and mathematicians, computer scientists, and philosophers who are interested in the applications of mathematical logic in their own field, as well as its interactions with other areas of research.
