It is well-known that the conformal structure of a relativistic spacetime is of profound physical and conceptual interest. In this note, we consider the analogous structure for Newtonian theories. We show that the Newtonian Weyl tensor is an invariant of this structure.

牛顿外尔张量的保形不变性

众所周知，相对论时空的共形结构具有深刻的物理和概念意义。在这篇笔记中，我们考虑了牛顿理论的类似结构。我们表明牛顿外尔张量是这种结构的不变量。
