Codazzi tensors and their space-times, and Cotton gravity
Carlo Alberto Mantica, Luca Guido Molinari
We study the geometric properties of certain Codazzi tensors for their own sake, and for their appearance in the recent theory of Cotton gravity. We prove that a perfect-fluid tens…
Spherical doubly warped spacetimes for radiating stars and cosmology
Carlo Alberto Mantica, Luca Guido Molinari
Spherically symmetric spacetimes are ambient spaces for models of stellar collapse and inhomogeneous cosmology. We obtain results for the Weyl tensor and the covariant form of the…
Geometric Perfect Fluids from Extended Gravity
Salvatore Capozziello, Carlo Alberto Mantica, Luca Guido Molinari
A main issue in cosmology and astrophysics is whether the dark sector phenomenology originates from particle physics, then requiring the detection of new fundamental components, or…
