Einstein's gravitational action and Fisher's information measure
We investigate an intriguing relation between (i) homogeneous and isotropic spatially flat cosmological models with no cosmological constant, on the one hand, and (ii) Fisher's information measure for translation families. An equivalence between that particular probability density that enters F...
