Resumen: During inflation, spacetime is approximately described by de Sitter space which is conformally invariant with the symmetry group SO(1,4). This symmetry can significantly constrain the quantum perturbations which arise in the inflationary epoch. We show how purely by these symmetry considerations, we can uniquely determine the three point function involving two scalar modes and one tensor mode.
