Abstract Intertheoretic reduction in physics aspires to be both to be explanatory and perfectly general: it endeavors to explain why an older, simpler theory continues to be as successful as it is in terms of a newer, more sophisticated theory, and it aims to relate or otherwise account for as many features of the two theories as possible. Despite often being introduced as straightforward cases of intertheoretic reduction, candidate accounts of the reduction of general relativity to Newtonian gravitation have either been insufficiently general or rigorous, or have not clearly been able to explain the empirical success of Newtonian gravitation. Building on work by Ehlers and others, I propose a different account of the reduction relation that is perfectly general and meets the explanatory demand one would make of it. In doing so, I highlight the role that a topology on the collection of all spacetimes plays in defining the relation, and how the selection of the topology corresponds with broader or narrower classes of observables that one demands be well-approximated in the limit.

关于广义相对论的减少到牛顿引力

摘要物理学中的跨理论还原渴望既能解释又能完全笼统：它试图解释为什么较旧的，更简单的理论继续像更新，更复杂的理论一样成功，并且其目的是联系或否则，要考虑两种理论的尽可能多的特征。尽管经常被介绍为理论简化的直接案例，但是关于牛顿引力的广义相对性降低的候选说明要么不够普遍或不够严格，要么不能清楚地解释牛顿引力的经验成功。在埃勒斯和其他人的工作的基础上，我提出了另一种关于还原关系的描述，该关系是完全笼统的并且满足人们对它的解释性要求。在这样做，
