Accelerated Expansion of the universe based on Particle Creation-Destruction Processes and Dark Energy in FLRW universes
Alberto C. Balfagon
Particle creation has been considered as a possible justification for the accelerated expansion of the universe, obeying the second law of thermodynamics, together with the possibl…
Cosmological Equations for Interacting Energies
Alberto C. Balfagon, Raul Ramirez-Satorras, Angel R. Martinez
In this paper the coupling between dark energy and the other components of the cosmological fluid has been studied. Firstly, it will be shown that the application of general cosmol…
Cosmological Equation of State and Interacting Energies
Alberto C. Balfagon, Raul Ramirez-Satorras
In this paper we study a model of cosmic evolution, assuming that the different components of the universe could interact between them any time. An effective equation of state (EOS…
Rainich theory applied to m-rank tensors in n-dimensions
Alberto C. Balfagon
We show a tensorial-computational way to find out conditions that must fulfil an m-rank tensor in arbitrary dimension in order to be algebraically the energy-momentum tensor of som…
Simplifying Tensor Polynomials with Indices
A. Balfagon, X. Jaen
We are presenting an algorithm capable of simplifying tensor polynomials with indices when the building tensors have index symmetry properties. These properties include simple symm…
