Extended disformal approach in the scenario of Rainbow Gravity
Gabriel G. Carvalho, Iarley P. Lobo, Eduardo Bittencourt
We investigate all feasible mathematical representations of disformal transformations on a space-time metric according to the action of a linear operator upon the manifold's tangen…
Space-time singularities in Weyl manifolds
I. P. Lobo, A. B. Barreto, C. Romero
We extend one of the Hawking-Penrose singularity theorems in general relativity to the case of some scalar-tensor gravity theories in which the scalar field has a geometrical chara…
On the disformal invariance of the Dirac equation
Eduardo Bittencourt, Iarley P. Lobo, Gabriel G. Carvalho
In this paper we analyze the invariance of the Dirac equation under disformal transformations depending on the propagating spinor field. Using the Weyl-Cartan formalism, we constru…
