论文摘要
我们研究了Lovelock和Horndeski重力理论的初始价值问题。我们表明，这些理论的运动方程可以以弱耦合形式编写，该形式是强烈双曲线的，因此接受了良好的初始值问题。这是通过引入新的“修改后的谐波”测量值来实现的，以实现一般相对论。
We study the initial value problem for Lovelock and Horndeski theories of gravity. We show that the equations of motion of these theories can be written in a form that, at weak coupling, is strongly hyperbolic and therefore admits a well-posed initial value problem. This is achieved by introducing a new class of "modified harmonic" gauges for general relativity.
