Resumen:
The classification of certain class of static solutions for theEinstein-Gauss-Bonnet theory in vacuum is performed in $dgeq5$ dimensions.The class of metrics under consideration is such that the spacelike section isa warped product of the real line and an arbitrary base manifold. It is shownthat for a generic value of the Gauss-Bonnet coupling, the base manifold mustbe necessarily Einstein, with an additional restriction on its Weyl tensor ford>5. The boundary admits a wider class of geometries only in the specialcase when the Gauss-Bonnet coupling is such that the theory admits a uniquemaximally symmetric solution. The additional freedom in the boundary metricenlarges the class of allowed geometries in the bulk, which are classifiedwithin three main branches, containing new black holes and wormholes in vacuum.
