First Order Extended Gravity and the Dark Side of the Universe: the General Theory
S. Capozziello, M. De Laurentis, M. Francaviglia +1
General Relativity is not the definitive theory of Gravitation due to several shortcomings which are coming out both from theoretical and experimental viewpoints. At large scales (…
Matter Lagrangians Coupled with Connections
L. Fatibene, M. Francaviglia, S. Mercadante
We shall here consider extended theories of gravitation in the metric-affine formalism with matter coupled directly to the connection. A sufficiently general procedure will be exhi…
Further Extended Theories of Gravitation: Part II
L. Fatibene, M. Ferraris, M. Francaviglia +1
We shall present and analyze two examples of extended theories of gravitation in Palatini formalism with matter that couples to the connection. This will show that the class of Fur…
Further Extended Theories of Gravitation: Part I
M. Di Mauro, L. Fatibene, M. Ferraris +1
We shall here propose a class of relativistic theories of gravitation, based on a foundational paper of Ehlers Pirani and Schild (EPS).All "extended theories of gravitation" (also…
Global Barbero-Immirzi Connections
L. Fatibene, M. Francaviglia
The Barbero-Immirzi (BI) connection, as usually introduced out of a spin connection, is a global object though it does not transform properly as a genuine connection with respect t…
General theory of Lie derivatives for Lorentz tensors
L. Fatibene, M. Francaviglia
We show how the ad hoc prescriptions appeared in 2001 by Ortin for the Lie derivative of Lorentz tensors are a direct consequence of the Kosmann lift defined earlier in 1996 in a m…
