As a consequence, these solutions are locally static: they admit an additional Killing vector that can either be space-like or time-like, depending on the position. This result also holds in the presence of an abelian gauge field, in which case the solutions are locally isometric to a charged static black hole.5 pagesGeneral Relativity and Quantum CosmologyHigh Energy Physics - TheoryBirkhoff's theorem in Lovelock gravitytext
