Query: Uniqueness of higher-dimensional phantom field wormholes   Based on the rigid positive energy theorem we proved the uniqueness of static
spherically symmetric traversable wormholes with two asymptotically flat ends,
being the higher-dimensional solutions of Einstein scalar phantom field. The
proof is valid under the auxiliary condition imposed on wormhole mass and
scalar charge.
