极值Reissner-Nordström黑洞上的Yang-Mills场

A Yang-Mills field on the extremal Reissner-Nordström black hole

Piotr Bizoń, Michał Kahl

摘要:

本文考虑球对称(磁)$SU(2)$ Yang-Mills场在极端Reissner-Nordström黑洞外的传播.利用共形对称性,我们将问题归结为具有两个渐近平坦端点的测地完备时空中的杨-米尔斯方程的研究。我们证明了无穷多个静态解的存在性(其中两个被发现在封闭形式),并确定其线性扰动和拟正规模式的频谱。最后,利用双曲逼近的初值问题,我们描述了松弛的过程中,各种初始数据的静态演化的最终状态。

英文摘要:

We consider a spherically symmetric (magnetic) $SU(2)$ Yang-Mills field propagating on the exterior of the extremal Reissner-Nordström black hole. Taking advantage of the conformal symmetry, we reduce the problem to the study of the Yang-Mills equation in a geodesically complete spacetime with two asymptotically flat ends. We prove the existence of infinitely many static solutions (two of which are found in closed form) and determine the spectrum of their linear perturbations and quasinormal modes. Finally, using the hyperboloidal approach to the initial value problem, we describe the process of relaxation to the static endstates of evolution for various initial data.
