A note on Harada's Conformal Killing gravity
Carlo Alberto Mantica, Luca Guido Molinari
We show that "Gravity at cosmological distances: Explaining the accelerating expansion without dark energy" recently proposed by J. Harada [6] is equivalent to the Einstein equatio…

The covariant approach to static spacetimes in Einstein and extended gravity theories
Carlo Alberto Mantica, Luca Guido Molinari
We present a covariant study of static space-times, as such and as solutions of gravity theories. By expressing the relevant tensors through the velocity and the acceleration vecto…
