On the hypotheses of Penrose's singularity theorem under disformal transformations
Eduardo Bittencourt, Gabriel G. Carvalho, Iarley P. Lobo +1
We analyze how the hypotheses of Penrose's singularity theorem (1965) are modified by the action of disformal transformations (defined in terms of light-like vectors) upon a given…
The geometry of null-like disformal transformations
Iarley P. Lobo, Gabriel G. Carvalho
Motivated by the hindrance of defining metric tensors compatible with the underlying spinor structure, other than the ones obtained via a conformal transformation, we study how som…
Scalar field self-force effects on a particle orbiting a Reissner-Nordstrom black hole
Donato Bini, Gabriel Carvalho, Andrea Geralico
Scalar field self-force effects on a scalar charge orbiting a Reissner-Nordström black hole are investigated. The scalar wave equation is solved analytically in a post-Newtonian fr…
