19. Slices of a four-geometry (Formula presented) can be obtained as surfaces (Formula presented), where (Formula presented) is a smooth real function on (Formula presented). These slices will have smooth geometries, except the slices passing through critical points where (Formula presented). The latter slices have singular geometries. A singular slice is nondegenerate if (Formula presented) at the corresponding critical point(s).
20. The corresponding slicing of (Formula presented) can be obtained by choosing (Formula presented), where (Formula presented) is the polar angle on one of the (Formula presented). Then, (Formula presented) everywhere, and the singular slices must be degenerate (see the preceding Ref. 13).

27. The Hartle-Hawking wave function gives the same particle production rate, since it predicts the same quantum state of the scalar field.
