Kantowski–Sachs metric

From Wikipedia, the free encyclopedia

In general relativity the Kantowski-Sachs metric (named after Ronald Kantowski and Rainer K. Sachs)[1] describes a homogeneous but anisotropic universe whose spatial section has the topology of . The metric is:

The isometry group of this spacetime is . Remarkably, the isometry group does not act simply transitively on spacetime, nor does it possess a subgroup with simple transitive action.
