The issue of the gauge invariance of gravitational waves arises if they are produced in the early universe at second-order in perturbation theory. We address it by dividing the discussion in three parts: The production of gravitational waves, their propagation in the real universe, and their measurement.

Abstract
The issue of the gauge invariance of gravitational waves arises if they are produced in the early universe at second-order in perturbation theory. We address it by dividing the discussion in three parts: The production of gravitational waves, their propagation in the real universe, and their measurement.File allegati a questo prodotto
