More about a successful vector-tensor theory of gravitation
Roberto Dale, Diego Sáez
The vector-tensor (VT) theory of gravitation revisited in this article was studied in previous papers, where it was proved that VT works and deserves attention. New observational d…
Approaches to relativistic positioning around Earth and error estimations
Neus Puchades, Diego Sáez
In the context of relativistic positioning, the coordinates of a given user may be calculated by using suitable information broadcast by a 4-tuple of satellites. Our 4-tuples belon…
Relativistic Positioning Systems: Numerical Simulations
Neus Puchades, Diego Sáez
The motion of satellite constellations similar to GPS and Galileo is numerically simulated and, then, the region where bifurcation (double positioning) occurs is appropriately repr…
Cosmology in a certain vector-tensor theory of gravitation
Roberto Dale, Diego Sáez
We study relevant cosmological topics in the framework of a certain vector-tensor theory of gravitation (hereafter VT). This theory is first compared with the so-called extended el…
Cosmological perturbations in extended electromagnetism. General gauge invariant approach
Roberto Dale, Diego Sáez
A certain vector-tensor (VT) theory is revisited. It was proposed and analyzed as a theory of electromagnetism without the standard gauge invariance. Our attention is first focused…
Probing the creatable character of perturbed Friedmann-Robertson-Walker universes
Ramon Lapiedra, Diego Sáez
We discuss whether some perturbed Friedmann-Robertson-Walker (FRW) universes could be creatable, i. e., could have vanishing energy, linear momentum and angular momentum, as it cou…
