examples

When there is time I will complete the set of examples

1. parallel tensors
2. parallel vector fields
3. recurrent vector fields on semiriemannian manifolds
4. metric space $\leftrightarrow$ recurrent conformal metric $\leftrightarrow$ weyl structure
5. recurrent curvature tensor $\leftrightarrow$ recurrent space-time
6. recurrent vectorfields are some generalisazion of pp-waves and appear in different context in general relativity

meaning of recurrent

Does anybody know, why these tensors are originally called recurrent? (have not read the full article by Walker yet)
In what sense is it recurring?
