Comment on Ricci Collineations of static spherically symmetric spacetimes
(SABER ULA, 2006-01-26)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 ... -
Cracking of self-gravitating compact objects with local and non local equations of state.
(SABER ULA, 2006-12-28)Cracking of self-gravitating compact objects with local and non local equations of state. (Abreu, Henso; Hernández, Hector y Núñez, Luis) Abstract We discuss the effect that small fluctuations of density and local ... -
Ecuaciones de estado no locales en relatividad general
(SABER ULA, Venezuela, 2009-11)En este trabajo se muestra que es posible obtener modelos físicamente aceptables para configuraciones de materia ultradensa, con simetría esférica, los cuales satisfacen una ecuación de estado no local. Este tipo particular ... -

Nonlocal equation of state in general relativistic radiating spheres
(SABER ULA, 2006-01-26)Nonlocal equation of state in general relativistic radiating spheres (Núñez, Luis; Hernández, Hector; Percoco, Umberto) Abstract We show that under particular circumstances a general relativistic spherically symmetric ... -
On the eccentricity behaviour of radiating slowly rotating bodies in general relativity
(SABER ULA, 2006-01-26)On the eccentricity behaviour of radiating slowly rotating bodies (Núñez, Luis; Hernández, Hector; Herrera, Luis; Percoco, Umberto) Abstract We study different models of radiating slowly rotating bodies up to the ... -

(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 ... -
Sound speeds, cracking and stability of self-gravitating anisotropic compact objects.
(SABER ULA, 2007-06-25)Sound speeds, cracking and stability of self-gravitating anisotropic compact objects. Abstract Using the the concept of cracking we explore the influence of density fluctuations and local anisotropy have on the stability ...
