Abstract

We introduce a class of proper posets which is preserved under countable support iterations, includes $\omega ^\omega $-bounding, Cohen, Miller, and Mathias posets associated to filters with the Hurewicz covering properties, and has the property that the ground model reals remain splitting and unbounded in corresponding extensions. Our results may be considered as a possible path towards solving variations of the famous Roitman problem.

关于分裂井集

我们引入了一类在可数支持迭代下保持的固有偏序集，包括$\omega ^\omega $ -bounding、Cohen、Miller和Mathias偏序集，这些偏序集与具有Hurewicz覆盖性质的滤波器相关联，并且在相应的扩展中具有地面模型实数保持分裂和无界的性质。我们的结果可能被认为是解决著名的Roitman问题的一个可能的途径。

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.
