For the transformation of spreads, we use an appropriate col lineation [see, e.g., Batten (1997)] of the pro jective space P . A collineation of PG (p − 1, q) is a permutation f of its points such that (t − 1)-dimensional subspaces are mapped to (t − 1)-dimensional subspaces for 1 ≤ t ≤ p.

Collineations, other than Motions, can be considered as non-noetherian symmetries and can also be associated to constants of the motion. Aﬃne Col lineations have been shown to be related to conserved quantities , and this property has been used to integrate geodesics of the Robertson-Walker metric .

Particular types of Ricci and Contracted Ricci Col lineations, for the Robertson-Walker metric have also been found and shown to be related to the particle number conservation .

It is clear from the above deﬁnitions that Motions are particular cases of Aﬃne Col lineations, Aﬃne Col lineations are particular cases of Curvature Col lineations, and so on.
Ricci Collineations for type B warped space-times
This result has been obtained with a simple application of the following theorem of pro jective geometry: if we have an ellipsoid (resp. an ellipse) and a sphere (resp. a circle), there exist col lineations that transform the ellipsoid (resp. the ellipse) into the sphere (resp. the circle).
