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 ...

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 (Núñez, Luis; Hernández, Hector; Herrera, Luis; Percoco, Umberto) Abstract We study different models of radiating slowly rotating bodies up to the ...

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 ...

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 ...

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 ...

Radiating, slowly rotating bodies in general relativity (Melfo, Alejandra; Núñez, Luis; Patiño, Alberto; Herrera, Luis) Abstract We propose a method to obtain axisymmetric, dynamic solutions to the Einstein equations ...
