Equivalence among frames in extended gravity
S. Capozziello, L. Fatibene, S. Garruto
We shall discuss equivalence of frames in Palatini f(R)-theories at action level. A Palatini formulation of Brans-Dicke theories (equivalent to the purely metric ones) will also be…
Extended Cosmologies
Salvatore Capozziello, Mariafelicia F. De Laurentis, Lorenzo Fatibene +2
We shall discuss cosmological models in extended theories of gravitation. We shall define a surface, called the model surface, in the space of observable parameters which character…
The Cauchy problem in General Relativity: An algebraic characterization
Lorenzo Fatibene, Simon Garruto
In this paper we shall analyse the structure of the Cauchy Problem (CP briefly) for General Relativity (GR briefly) by applying the theory of first order symmetric hyperbolic syste…
