We calculate the gravitational energy spectrum of the perturbations of a Schwarzschild black hole described by quasinormal modes, in the framework of the teleparallel equivalent of general relativity (TEGR). We obtain a general formula for the gravitational energy enclosed by a large surface of constant radius r, in the region $m<<r<<\infty$, where m is the mass of the black hole. Considering the usual asymptotic expression for the perturbed metric components, we arrive at finite values for the energy spectrum. The perturbed energy depends on the two integers n and l that describe the quasinormal modes. In this sense, the energy perturbations are discretized. We also obtain a simple expression for the decrease of the flux of gravitational radiation of the perturbations.

TEGR中引力的扰动：Schwarzschild黑洞的准正态模式

我们在广义相对论（TEGR）的平行平行等效框架内，计算了准准模式所描述的Schwarzschild黑洞的摄动的引力能谱。我们获得用于由恒定半径的一个大的表面围成的引力能的通式[R ，在该区域$米<<\mathrm{[R}<<\infty$，其中m是黑洞的质量。考虑到扰动的度量分量的通常渐近表达式，我们得出了能谱的有限值。扰动的能量取决于描述准正态模的两个整数n和l。从这个意义上讲，能量扰动是离散的。对于扰动的重力辐射通量的减少，我们也获得了一个简单的表达式。
