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 $e_{\mu }^I$ and a $Spin(3,1)$-conn…
