Evolving extrinsic curvature and the cosmological constant problem
Abraao J. S. Capistrano, Luiz A. Cabral
The concept of smooth deformation of Riemannian manifolds associated with the extrinsic curvature is explained and applied to the FLRW cosmology. We show that such deformation can…
Smooth deformations and cosmic statefinders
A. J. S Capistrano
We study the possibility that the universe is subjected to a deformation, besides its expansion described by Friedmann's equations. The concept of smooth deformation of a riemannia…
Weyl conformastatic perihelion advance of small body objects
Abraao J. S. Capistrano, Waldir L. Roque, Rafael S. Valada
In this paper, we examine a static gravitational field with axial symmetry over probe particles in the solar system. Using the Weyl conformastatic solution as a model, we find a no…
