Spherical symmetric dust collapse in a Vector-Tensor gravity
R. Dale, D. Sáez
There is a viable vector-tensor gravity (VTG) theory, whose vector field produces repulsive forces leading to important effects. In the background universe, the effect of these for…
A generalized permutation entropy for random processes
José M. Amigó, Roberto Dale, Piergiulio Tempesta
Permutation entropy measures the complexity of deterministic time series via a data symbolic quantization consisting of rank vectors called ordinal patterns or just permutations. T…
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…
Proposal for the origin of the cosmological constant
R. Dale, J. A. Morales-Lladosa, D. Saez
We work in the framework of a simple vector-tensor theory. The parametrized post-Newtonian approximation of this theory is identical to that of general relativity. Our attention is…
