摘要：

The behavior of gravitational wave perturbations on a locally Minkowskian spacetime background containing a planar domain wall is investigated in the gauge-invariant general-relativistic framework. It is shown that for this particular background the domain wall does not emit gravitational waves spontaneously by its free oscillation in the first order, although it scatters incidental gravitational waves. This suggests that the amplitude of gravitational waves emitted from a domain wall is at least of second order in the oscillation amplitude of the domain wall. © 1994 The American Physical Society.
