抄録: | The Bristol model is an inner model of L[c], where c is a Cohen real, which is not constructible from a set. The idea was developed in 2011 in a workshop taking place in Bristol, but was only written in detail by the author in [8]. This paper is meant as a guide for those who want to get a broader view of the construction. We try to provide more intuition that might serve as a jumping board for those interested in this construction and in odd models of ZF. We also correct a few minor issues in the original paper, as well as prove new results. For example, that the Boolean Prime Ideal theorem fails in the Bristol model, as some sets cannot be linearly ordered. In addition to this we include a discussion on Kinna-Wagner Principles, which we think may play an important role in understanding the generic multiverse in ZF. |
