The Wave Function of the Universe and CMB Fluctuations
  The Hartle-Hawking and Tunneling (Vilenkin) wave functions are treated in the
Hamiltonian formalism. We find that the leading (i.e. quadratic) terms in the
fluctuations around a maximally symmetric background, are indeed Gaussian
(rather than inverse Gaussian), for both types of wave function, when properly
interpreted. However the suppression of non-Gaussianities and hence the
recovery of the Bunch-Davies state is not transparent.
