Propagation amplitude in homogeneous quantum cosmology
Description
A study is presented of Teitelboim's [1982, Phys. Rev.D 25,3159] propagation amplitude of quantum gravity in spatially homogeneous spacetimes of class A. In the case of Bianchi types IX and VIII, the amplitude is given by averaging a Green function of the superHamiltonian operator over spatial coordinate transformations. For the remaining class A types, the amplitude depends on the choice of spatial coordinates. The amplitude is evaluated analytically at the isotropic limit of type IX. The physical interpretation is discussed. (author)
