渐近AdS时空中的大质量波动方程

The massive wave equation in asymptotically AdS spacetimes

C. M. Warnick

摘要:

考虑渐近AdS空间上的有质量波动方程.我们表明,类时scri的行为就像一个有限的类时边界上,其中一个可以施加相当于狄利克雷,诺依曼或罗宾条件的范围内(负)的质量参数,其中包括共形耦合的情况。我们证明了相关的初边值问题在$H^1$水平的正则性适定性。我们还证明了更高的正则性可以得到,连同一个渐近展开的领域附近的scri。证明依赖于能量方法,适合于Breitenlohner和Freedman引入的修正能量。我们不假定时空是静止的,也不假定波动方程是分离的。

英文摘要:

We consider the massive wave equation on asymptotically AdS spaces. We show that the timelike scri behaves like a finite timelike boundary, on which one may impose the equivalent of Dirichlet, Neumann or Robin conditions for a range of (negative) mass parameter which includes the conformally coupled case. We demonstrate well posedness for the associated initial-boundary value problems at the $H^1$ level of regularity. We also prove that higher regularity may be obtained, together with an asymptotic expansion for the field near scri. The proofs rely on energy methods, tailored to the modified energy introduced by Breitenlohner and Freedman. We do not assume the spacetime is stationary, nor that the wave equation separates.
