我们构造了一个模自由的M-理论的背景。这个背景随后被证明与E8(8)例外场论(ExFT)的一个拓扑相有关。结构中的关键成分是在ExFT中嵌入非黎曼几何。这使得人们可以使用最初为描述最大超重力而开发的ExFT框架来描述非相对论几何,如牛顿-卡坦或戈米斯-乌古里类型的极限。这在双场理论的背景下推广了Morand和Park之前的工作。
We construct a background for M-theory that is moduli free. This background is then shown to be related to a topological phase of the E 8 (8) exceptional field theory (ExFT). The key ingredient in the construction is the embedding of non-Riemannian geometry in ExFT. This allows one to describe non-relativistic geometries, such as Newton-Cartan or Gomis-Ooguri-type limits, using the ExFT framework originally developed to describe maximal supergravity. This generalises previous work by Morand and Park in the context of double field theory.
