Ricci collineations for non-degenerate, diagonal and spherically symmetric ricci tensors
(SABER ULA, 2006-01-26)Ricci collineations for non-degenerate, diagonal and spherically symmetric ricci tensors (Núñez, Luis; Percoco, Umberto; Contreras, Gerardo) Abstract The expression of the vector field generator of a Ricci Collineation ... -
Ricci collineations for type B warped space-times
(SABER ULA, 2006-01-26)Ricci collineations for type B warped space-times (Núñez, Luis; Percoco, Umberto; Carot, J.) Abstract We present the general structure of proper Ricci Collineations (RC) for type B warped space-times. Within this ... -
