We discuss the status of gravitational radiation in Newtonian theories. In order to do so, we (i) consider various options for interpreting the Poisson equation as encoding propagating solutions, (ii) reflect on the extent to which limit considerations from general relativity can shed light on the Poisson equation’s conceptual status, and (iii) discuss various senses in which the Poisson equation counts as a (non-)dynamical equation.

牛顿引力辐射的现状

我们讨论了牛顿理论中的重力辐射的状况。为此，我们（i）考虑将Poisson方程解释为编码传播解的各种选择，（ii）考虑广义相对论的极限考虑可以在多大程度上阐明Poisson方程的概念状态，以及（iii） ）讨论了各种意义，其中泊松方程算作一个（非）动力学方程。
