The latter allows us to compare vectors and tensors at different points. The generalization of symmetry transformations with Killing fields is also introduced.

Finally, the small curvature limit in which the Einstein field equations are linear is worked out. This establishes the contact with the other classical field theory, Maxwell electrodynamics.

In addition we must tie the latter to the attendant partial pressures via suitable equations of state . .. This is the program of the current chapter.
