The role of translational invariance in non linear gauge theories of gravity
J. Martin, A. Tiemblo
The internal structure of the tetrads in a Poincaré non linear gauge theory of gravity is considered. Minkowskian coordinates becomes dynamical degrees of freedom playing the role…
General structure of the solutions of the Hamiltonian constraints of gravity
J. Martin, Antonio F. Rañada, A. Tiemblo
A general framework for the solutions of the constraints of pure gravity is constructed. It provides with well defined mathematical criteria to classify their solutions in four cla…
On Mach's principle: Inertia as gravitation
J. Martin, Antonio F. Ranada, A. Tiemblo
In order to test the validity of Mach's principle, we calculate the action of the entire universe on a test mass in its rest frame, which is an acceleration . We show th…
Spherically symmetric dissipative anisotropic fluids: A general study
L. Herrera, A. Di Prisco, J. Martin +3
The full set of equations governing the evolution of self--gravitating spherically symmetric dissipative fluids with anisotropic stresses is deployed and used to carry out a genera…
Anisotropic geodesic fluid spheres in general relativity
L. Herrera, J. Martin, J. Ospino
It is shown that unlike the perfect fluid case, anisotropic fluids (principal stresses unequal) may be geodesic, without this implying the vanishing of (spatial) pressure gradients…
