Static wormholes in vacuum for conformal gravity

Julio Oliva, David Tempo, Ricardo Troncoso

A static spherically symmetric wormhole solution for conformal gravity in vacuum is found. The solution possesses a single integration constant which determines the size of the nec…

Static spherically symmetric solutions for conformal gravity in three dimensions

Julio Oliva, David Tempo, Ricardo Troncoso

Static spherically symmetric solutions for conformal gravity in three dimensions are found. Black holes and wormholes are included within this class. Asymptotically the black holes…

Kerr-Schild ansatz in Einstein-Gauss-Bonnet gravity: An exact vacuum solution in five dimensions

Andres Anabalon, Nathalie Deruelle, Yoshiyuki Morisawa +4

As is well-known, Kerr-Schild metrics linearize the Einstein tensor. We shall see here that they also simplify the Gauss-Bonnet tensor, which turns out to be only quadratic in the…

Interacting cosmic fluids in power-law Friedmann-Robertson-Walker cosmological models

Mauricio Cataldo, Patricio Mella, Paul Minning +1

We provide a detailed description for power--law scaling Friedmann-Robertson-Walker cosmological scenarios dominated by two interacting perfect fluid components during the expansio…

Invariant conserved currents for gravity

Yuri N. Obukhov, Guillermo F. Rubilar

We develop a general approach, based on the Lagrange-Noether machinery, to the definition of invariant conserved currents for gravity theories with general coordinate and local Lor…

Invariant conserved currents in gravity theories: diffeomorphisms and local gauge symmetries

Yuri N. Obukhov, Guillermo F. Rubilar

Previously, we have developed a general method to construct invariant conserved currents and charges in gravitational theories with Lagrangians that are invariant under spacetime d…
