Lorentzian Regge Calculus and Spinfoam: an example with fixed Topology — •Dimitri Marinelli1 and Giorgio Immirzi2 — 1Dipartimento di Fisica, Università degli Studi di Pavia, Pavia, Italy — 2Colle Ballone, Montopoli di Sabina, Italy
Regge Calculus is the classical starting point for a bunch of different models of Quantum Gravity. I will present two different solutions of this classical model of gravity for a fixed topology. Some interesting aspects and open problems related to the Lorentzian structure of the discrete system will be analyzed. Moreover, I will present the first steps towards the implementation of the Spinfoam Quantization based on these classical solutions of the Regge Calculus.
