Why do we live in a Riemannian space time ?
Roberto Scipioni
We start from the pure Einstein-Hilbert action in Metric Affine Gravity, with the orthonormal metric. We get an effective Levi-Civita Dilaton gravity theory in which the Dilaton fi…

Non-Riemannian Gravitation amd its relation with Levi-Civita theories
Roberto Scipioni
The mathematical relations between certain classical Non-Riemannian gravity models and Einstein-Proca theories are discussed in details. We also show some relations with theories w…
