标题： Static de-Sitter Black Holes Abhor Charged Scalar Hair

摘要： 我们证明了在de-Sitter时空事件视界和宇宙学视界之间的区域，静态黑洞没有带电标量毛发定理。 该证明不依赖于球对称性的假设。 它允许标量场与引力和电磁场的广义非最小耦合函数，以及爱因斯坦引力的高曲率项修正。 通过要求适当的边界条件，该结果可扩展到其他渐近时空。 我们的结果排除了静态带电de-Sitter黑洞周围自发标量化的可能性。 显示英文摘要

摘要： We prove a no charged scalar hair theorem for static black holes in de-Sitter spacetime in the region between the event horizon and the cosmological horizon. The proof does not depend on the assumption of spherical symmetry. It allows for general non-minimal coupling functions of the scalar field to gravity and electromagnetic fields, and for higher curvature term corrections to Einstein gravity. The extension to other asympitotic spacetimes is applicable by requiring appropriate boundary conditions. Our result excludes the possibility for spontaneous scalarization of charged scalar around static charged de-Sitter black holes.
