Existence of stable hairy black holes in su(2) Einstein-Yang-Mills theory with a negative cosmological constant
... ξ sufficiently small, the solution will remain close to its values for ξ = 0, until r ≫ 1 and p(r)/r ≪ 1/ | Λ | . In particular, ω will have no nodes in this regime. Since m(r)/r ≪ 1, we may consider the asymptotic ...
