Uniqueness theorem for stationary black ring solution of $σ$-models in five dimensions
Abstract
Description
We study axisymmetric self-gravitating non-linear $σ$-model in five-dimensional spacetime admitting three commutating Killing vector fields. We show that the only asymptotically flat black ring solution with a regular event horizon is the black ring characterized by mass and two angular momenta with constant mapping.
