Boost invariance of the gravitational field dynamics: quantization without time gauge

General Relativity and Quantum Cosmology 2008-11-26 v1

Abstract

We perform a canonical quantization of gravity in a second-order formulation, taking as configuration variables those describing a 4-bein, not adapted to the space-time splitting. We outline how, neither if we fix the Lorentz frame before quantizing, nor if we perform no gauge fixing at all, is invariance under boost transformations affected by the quantization.
