我们解决的行为与负质量平方的标量场在五维AdS空间的Randall-Sundrum膜世界嵌入。我们指出，快子标量允许在散装空间不稳定的嵌入膜世界的宇宙常数为零。从AdS/CFT对应的角度讨论了这种不稳定性的解决方法。
We address the behaviour of the scalar field with negative mass squared in the five dimensional AdS space where the Randall-Sundrum brane-world is embedded. We point out that the tachyonic scalar allowed in the bulk space destabilizes the embedded brane-world where the cosmological constant is zero. The resolution of this instability is discussed from the viewpoint of AdS/CFT correspondence.
