Abstract

Comment on Ricci Collineations of static spherically symmetric spacetimes (Núñez, Luis; Contreras, Gerardo; Percoco, Umberto; Bertolotti, Ricardo; Carot, J.)

Abstract

We present a counter example to a theorem given by Amir et al. J. Math. Phys. 35, 3005 (1994). We also comment on a misleading statements of the same reference.
