Abstract

The paper presents some general relations obtaining in relativistic cosmology. It appears from these that a simple change over to anisotropy without the introduction of spin does not solve any of the outstanding difficulties of isotropic cosmological models.

Discussions

• First: if the indexing on $B$ is in "backwards" order, then it's probably because it was common to write the covariant derivative as $B_{ab} = u_{a;b}$ , rather than $B_{ab} = ∇_b u_a$ . Strictly spea [stackexchange, 1 points]
