Ricci Collineations for Non-Degenerate, Diagonal and Spherically Symmetric Ricci Tensors
G. Contreras, L. A. Núñez, U. Percoco
The expression of the vector field generator of a Ricci Collineation for diagonal, spherically symmetric and non-degenerate Ricci tensors is obtained. The resulting expressions sho…

Comment on Ricci Collineations of Static Spherically Symmetric Spacetimes
R. Bertolotti, G. Contreras, L. A. Núñez +2
We present a counter example to a theorem given by Amir {\em et al.} J. Math. Phys. {\bf 35}, 3005 (1994). We also comment on a misleading statements of the same reference.
