Lecture Notes in Loop Quantum Gravity. LN2: Cauchy problems and pre-quantum states

S. Coriasco, L. Fatibene, S. Garruto +1

We discuss the structure of covariant equations, relating analytical properties of solutions to algebraic properties of the corresponding differential operator, specifically of its…

Introduction to Loop Quantum Gravity. The Holst's action and the covariant formalism

L. Fatibene, A. Orizzonte, A. Albano +4

We review Holst formalism and we discuss dynamical equivalence with standard GR (in dimension 4). Holst formalism is written for a spin coframe field and a -conn…

Principal Symbol of Euler-Lagrange Operators

Lorenzo Fatibene, Simon Garruto

We shall introduce the principal symbol for Euler-Lagrange operators and use them to charac- terise well-posed initial value problems. We shall clarify how constraints can arise in…

Extended Theories of Gravitation

Lorenzo Fatibene, Simon Garruto

In this paper we shall review the equivalence between Palatini theories and Brans- Dicke (BD) theories at the level of action principles. We shall define the Helmho…

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…
