Equivalence of Grandfather and Information Antinomy Under Intervention

论文摘要
因果循环，例如在时间旅行中，带来了两个主要问题。最突出的是，祖父的反触及症描述了矛盾的潜力：逻辑性质的问题。另一个问题称为信息抗原症，鲜为人知。然而，它描述了前者的一种变体：没有太少的一致解决方案 - 即没有 - 但太多。乍看之下，信息反触及术似乎不如祖父反触及术，因为没有明显的逻辑矛盾。但是，在这项工作中，我们表明，这两个问题在干预措施下都是等效的：如果当事方可以以信息反触及的方式进行干预，那么它们也可以干预以产生矛盾，反之亦然。
Causal loops, e.g., in time travel, come with two main problems. Most prominently, the grandfather antinomy describes the potentiality to inconsistencies: a problem of logical nature. The other problem is called information antinomy and is lesser known. Yet, it describes a variant of the former: There are not too few consistent solutions -- namely none -- but too many. At a first glance, the information antinomy does not seem as problematic as the grandfather antinomy, because there is no apparent logical contradiction. In this work we show that, however, both problems are equivalent under interventions: If parties can intervene in such a way that the information antinomy arises, then they can also intervene to generate a contradiction, and vice versa.
