J. Bjoraker et Y. Hosotani, Stable monopole and dyon solutions in the Einstein-Yang-Mills theory in asymptotically anti-de Sitter space, PHYS REV L, 84(9), 2000, pp. 1853-1856
A continuum of new monopole and dyon solutions in the Einstein-Yang-Mills t
heory in asymptotically anti-de Sitter space are found. They are regular ev
erywhere and specified by their mass and their non-Abelian electric and mag
netic charges. A class of monopole solutions which have no node in non-Abel
ian magnetic fields is shown to be stable against spherically symmetric Lin
ear perturbations.
