论文摘要
Haag的定理呼吁解释和批判性评估：听起来有些警报是（也许）在构造相互作用的标准方式之一中，某种方法是不正确的，用于为散射实验生成预测。关于问题，适当解决方案的确切性质以及随后在物理，数学和哲学领域的发展方面的观点差异很大。在本文中，我们开发并部署了一个概念框架，以批判性地评估对Haag定理的这些不同的反应。这样做揭示了有关物理学基础工作的性质和目的的更一般性问题的推动力。
Haag's theorem cries out for explanation and critical assessment: it sounds the alarm that something is (perhaps) not right in one of the standard way of constructing interacting fields to be used in generating predictions for scattering experiments. Viewpoints as to the precise nature of the problem, the appropriate solution, and subsequently-called-for developments in areas of physics, mathematics, and philosophy differ widely. In this paper, we develop and deploy a conceptual framework for critically assessing these disparate responses to Haag's theorem. Doing so reveals the driving force of more general questions as to the nature and purpose of foundational work in physics.
