We apply the BDLI method for the Hamiltonian system, and a new energy-preserving method is obtained. The new method is symmetric and can preserve the Hamiltonian up to round-off error.
WebA positive ζ(0) value in these cases ensures that, when the three-sphere boundary approaches zero, the resulting one-loop wave function approaches zero. This property may be interpreted by saying that, in the limit of small three-geometry, the resulting one-loop wave function describes a singularity-free universe.
