~ 1999年11月5日收到; 2000年8月24日收到修订稿; 2000年11月14日出版！研究了具有奇宇称畸变的非旋转黑洞的完全非线性微扰演化。微扰方法被证明是有用的，以解释非线性的结果。特别是，他们提供了洞察的波形与失真参数Q 0的非线性依赖性，解释它的多极耦合。我们还发现，在非线性制度的波形的频率的增加，这是由于损失的显着的一部分，系统的初始总质量的引力辐射产生有效的漂移的quasinormal频率。非线性演化已经完成~并进行了交叉检查！与三维并行代码的数值相对论，CACTUS，和一个独立的轴对称代码MAGOR。使用Regge-Wheeler形式主义的线性化。
~Received 5 November 1999; revised manuscript received 24 August 2000; published 14 November 2000! We study fully nonlinear and perturbative evolutions of nonrotating black holes with odd-parity distortions. Perturbative methods proved to be useful in order to interpret the nonlinear results. In particular, they provided insight on the nonlinear dependence of the wave forms with the distortion parameter Q0, explaining it in terms of the multipole coupling. We also found an increase in the frequency of the wave forms in the nonlinear regime which results from the loss of a noticeable part of the initial total mass of the system to gravitational radiation producing effectively a drifting of the quasinormal frequencies. The nonlinear evolutions have been performed ~and cross checked! with the 3D parallel code for numerical relativity, CACTUS, and an independent axisymmetric code MAGOR. The linearized ones using the Regge-Wheeler formalism.
