论文摘要

什么(如果有的话)可以帮助我们解释物质的动态行为?在这里,可能会诱使人们呼吁自然法则,世界几何结构,甚至呼吁时空歧管本身的平滑拓扑结构。但是,有些人认为,这种解释性策略所涉及的形而上学过于怪异。确实,有些人选择扭转解释的箭头,将动态放在首位。例如,人们可以使用刘易斯的最佳系统分析(BSA)将自然定律视为物质动态行为中某些模式的编码。同样,人们可以使用Huggett的规律性关系来实现对世界几何结构的类似观点。然而,目前,空间歧管本身还没有这样的动态优先观点。本文提出了这样的观点:时空流形只是物质动力学行为中某些模式的编纂。 该论文开发了强大的数学工具,用于研究和谈判各种时空环境之间为广泛的时空理论进行谈判。从这里开始,引用了不同时空编码之间的竞争,类似于刘易斯的BSA中不同法律般的编码之间的竞争。尽管BSA根据其简单性和强度的平衡来法官法律般的编码,但时空的编码应根据其适合理论的动力学和运动学能力来判断。

What, if anything, can help us explain the dynamical behavior of matter? One may be tempted here to appeal to the laws of nature, or to the world's geometric structure, or even to the smooth topological structure of the spacetime manifold itself. Some think, however, that the metaphysics involved in such explanatory strategies is excessively spooky. Indeed, some opt to reverse the arrow of explanation, putting dynamics first. For instance, one can use Lewis's Best Systems Analysis (BSA) to view the laws of nature as merely being codifications of certain patterns in the dynamical behavior of matter. Similarly, one can use Huggett's Regularity Relationism to achieve an analogous view of the world's geometric structure. At present, however, there is no such dynamics-first view of the spacetime manifold itself. This dissertation puts forward such a view: The spacetime manifold is merely a codification of certain patterns in the dynamical behavior of matter. This dissertation develops powerful mathematical tools for investigating and negotiating between a wide variety of spacetime settings for a wide range of spacetime theories. From here, a competition between different spacetime codifications is invoked analogous to the competition between different law-like codifications in Lewis's BSA. Whereas the BSA judges law-like codifications based on their balance of simplicity and strength, spacetime codifications are to be judged by how well they fit the theory's dynamics and kinematics.
