Lie-algebra expansions, Chern-Simons theories and the Einstein-Hilbert lagrangian
José D. Edelstein, Mokhtar Hassaïne, Ricardo Troncoso +1
Starting from gravity as a Chern-Simons action for the AdS algebra in five dimensions, it is possible to deform the theory through an expansion of the Lie algebra that leads to a s…
Quasinormal modes for massless topological black holes
Rodrigo Aros, Cristian Martinez, Ricardo Troncoso +1
An exact expression for the quasinormal modes of scalar perturbations on a massless topological black hole in four and higher dimensions is presented. The massive scalar field is n…
Supersymmetric extension of the nine-dimensional continuation of the Euler density with N=2
Mokhtar Hassaine, Rodrigo Olea, Ricardo Troncoso
A local supersymmetric extension with N=2 of the dimensional continuation of the Euler-Gauss-Bonnet density from eight to nine dimensions is constructed. The gravitational sector i…
Conserved charges for gravity with locally AdS asymptotics
Rodrigo Aros, Mauricio Contreras, Rodrigo Olea +2
A new formula for the conserved charges in 3+1 gravity for spacetimes with local AdS asymptotic geometry is proposed. It is shown that requiring the action to have an extremum for…
