通过数值求解具有负宇宙学常数的四维球对称Einstein-mass-scalar场方程，研究了弱扰动反德西特（AdS）空间的非线性演化.我们的结果表明，AdS空间是不稳定的任意小的一般扰动。我们推测，这种不稳定性是由共振模式混合引起的能量从低到高的频率扩散。
We study the nonlinear evolution of a weakly perturbed anti-de Sitter (AdS) space by solving numerically the four-dimensional spherically symmetric Einstein-massless-scalar field equations with negative cosmological constant. Our results suggest that AdS space is unstable under arbitrarily small generic perturbations. We conjecture that this instability is triggered by a resonant mode mixing which gives rise to diffusion of energy from low to high frequencies.
