Geometry and stability of spinning branes in AdS gravity

The geometry of spinning codimension-two branes in anti-de Sitter (AdS) spacetime is analyzed in three and higher dimensions. The construction of nonextremal solutions is based on identifications in the covering of AdS space by isometries that have fixed points. The discussion focuses on the cases w...
