Dynamics of quadratic f(R) cosmology with a perfect fluid: Jordan and Einstein frames
Artur Alho, Margarida Lima, Filipe C. Mena
We investigate the global dynamics of the field equations of (pure) quadratic theories of gravity which generalise Einstein's theory in spatially flat homogeneous and isotropic cos…
Energy bounds and ergoregion instability in Einstein-Maxwell-Scalar field models
Filipe C. Mena, João M. Oliveira
We investigate energy bounds and the stability of stationary asymptotically flat spacetimes with an ergoregion and no future horizon in the context of Einstein-Maxwell-Scalar field…
A first-order formulation of f(R) gravity in spherical symmetry
Philippe G. LeFloch, Filipe C. Mena
We develop an augmented characteristic, first-order formulation of the field equations in f(R) gravity governing the global evolution of a (possibly) massive scalar field phi under…
Local well-posedness of the initial value problem in Einstein-Cartan theory
Paulo Luz, Filipe C. Mena
We study the initial value problem in Einstein-Cartan theory which includes torsion and, therefore, a non-symmetric connection on the spacetime manifold. Generalizing the path of a…
Asymptotics of spin-0 fields and conserved charges on n-dimensional Minkowski spaces
Edgar Gasperín, Mariem Magdy, Filipe C. Mena
We use conformal geometry methods and the construction of Friedrich's cylinder at spatial infinity to study the propagation of spin- fields (solutions to the wave equation) on $…
