Query: Existence of stable hairy black holes in su(2) Einstein-Yang-Mills
  theory with a negative cosmological constant   We consider black holes in EYM theory with a negative cosmological constant.
The solutions obtained are somewhat different from those for which the
cosmological constant is either positive or zero. Firstly, regular black hole
solutions exist for continuous intervals of the parameter space, rather than
discrete points. Secondly, there are non-trivial solutions in which the gauge
field has no nodes. We show that these solutions are linearly stable.
