标题： Peculiarities for scalar fields in GR domain walls

摘要： 在本信中，研究了无限域壁时空中的克莱因-戈登方程的解。 显示视界是一个特殊区域，在该区域中无法定义场在渐近过去处的初始条件（散射条件）。 这与该区域无法穿越的事实一致，这一可能性在\cite{lanosa}中被提出。 如果这些结果正确，那么在此位置施加边界条件是没有意义的。 显示英文摘要

摘要： In the present letter, the solutions of the Klein Gordon equation in the space time of an infinite domain wall is studied. It is shown that the horizon is an special region, where initial conditions (scattering conditions) at asymptotic past for the field can not be defined. This is in harmony with the fact that this region can not be crossed, a possibility that was suggested in \cite{lanosa}. If these results are correct, then it makes no sense to impose boundary conditions at this location.
