Abstract
An expression for the functional determinant on a sphere for a massive (scalar) field derived by Denef, Hartnoll and Sachdev using quasinormal modes is shown to exist already in the literature together with the multiplicative anomaly interpretation. The relevant expressions are outlined and several equivalent versions are given. The variation with mass is determined numerically. As an application of the derived formulae, the Hartle--Hawking probability of the Universe (via the dS/CFT correspondance) is recomputed. Agreement is found with Anninos, Denef and Harlow. The calculation is extended to all (odd) dimensions. I also compute the wave function which reveals an interesting feature.
