Emergence of Dark Energy from topology and chiral spinors
J. Lorca Espiro, Yerko Vásquez, M. Le Delliou
Under the existence of a massless spinor with respect to the total connection in a spacetime modeled as a Lorentzian manifold with internal boundaries, such as finite volume semi-c…
Dark Energy from Topology
J. Lorca Espiro, M. Le Delliou
The concordance model of cosmology suffers from the major theoretical problems surrounding the observed value and recent emergence of a cosmological constant. In this paper we pres…
Is the Cosmological Constant of Topological Origin?
M. Le Delliou, J. Lorca Espiro
The observed value of the cosmological constant poses large theoretical problems. We find that topology of the Universe provides a natural source for it. Restricting dynamically an…
A topological origin for Dark Energy
J. Lorca Espiro, Morgan Le Delliou
Cosmology struggles with the theoretical problems generated by the observed value and recent emergence of a cosmological constant, in the standard model of cosmology, i.e. the conc…
Some cosmological models coming from gravitational theories having torsional degrees of freedom
J. Lorca Espiro, Yerko Vásquez
In this work we consider gravitational theories in which the effect of coupling characteristic classes, appropriately introduced as operators in the Einstein-Hilbert action, has be…
