Global hyperbolicity helps ensure that cause comes before effect in a spacetime model.
全局双曲性有助于确保在一个时空模型中“因”先于“果”。
In many textbooks, global hyperbolicity is used to guarantee the well-posedness of the initial value problem for fields on curved spacetime.
在许多教材中,全局双曲性被用来保证曲率时空上场的初值问题是良定的(解的存在、唯一性与连续依赖性)。
