Breaking the Conformal Gauge by Fixing Time Protocols
Lorenzo Fatibene, Simon Garruto, Maurizio Polistina
We review the definition by Perlick of standard clocks in a Weyl geometry and show how a congruence of clocks can be used to fix the conformal gauge in the EPS framework. Examples…

Extended Gravity
L. Fatibene, S. Garruto
We shall show equivalence between Palatini-$f(\calR)$ theories and Brans-Dicke (BD) theories at the level of action principles in generic dimension with generic matter coupling. We…

Do Barbero-Immirzi connections exist in different dimensions and signatures?
L. Fatibene, M. Francaviglia, S. Garruto
We shall show that no reductive splitting of the spin group exists in dimension 3 \leq m \leq 20 other than in dimension m = 4. In dimension 4 there are reductive splittings in any…
