| Abstract: | The canonical formulation of the Hartle-Hawking proposal is discussed in a class of spatially homogeneous minisuperspace model. Relying on arguments of consistency with the classical variational principle, we find a set of canonical variables in which the Hartle-Hawking boundary condition is obtained by fixing in the path integral the final values of the canonical coordinates but the initial values of the canonical momenta. A canonical measure of this kind offers a natural starting point for skeletonising the minisuperspace Hartle-Hawking path integral. |
