We study the Fourier transform of the two differential operators in the non-relativistic case in the presence of the Bunch-Davies term. It is shown that in the torsion-free case the two differential operators are the same. We also show that in the conservation case the two differential operators are different. We then describe the Fourier transform of the two differential operators in the relativistic case and show that the two differential operators are the same.
