| Resumo | |
We investigate the properties of spherically symmetric black-hole solutions in the generalized Einstein-Skyrme model theory in four-dimensional asymptotically anti-de Sitter spacetime. The dependences of the Skyrmion fields on the cosmological constant and on the strength of the effective gravitational coupling are examined. We show that the increase of the absolute value of the cosmological constant qualitatively yields the same effect as increasing the effective gravitational coupling. We confirm that, similar to the model in asymptotically flat spacetime, a necessary condition for the existence of black holes with Skyrmionic hair is the inclusion of the Skyrme term. (AU) | |
