Could the black hole singularity be a field singularity?
Guillem Domènech, Atsushi Naruko, Misao Sasaki +1
In the wake of interest to find black hole solutions with scalar hair, we investigate the effects of disformal transformations on static spherically symmetric space-times with a no…

On metric transformations with a gauge field
Antonio De Felice, Atsushi Naruko
We study metric transformations including not just the field strength tensor of a gauge field, but also its dual tensor. We first consider an arbitrary symmetric matrix buil…

Possible resolution of a spacetime singularity with field transformations
Atsushi Naruko, Chul-Moon Yoo, Misao Sasaki
It is widely believed that classical gravity breaks down and quantum gravity is needed to deal with a singularity. We show that there is a class of spacetime curvature singularitie…
