On Shift Dynamics for Cyclically Presented Groups
Bogley, William A.
A group defined by a finite presentation with cyclic symmetry admits a shift automorphism
that is periodic and word-length preserving. It is shown that if the presentation
is combinatorially aspherical and orientable, in the sense that no relator is
a cyclic permutation of the inverse of any of its shifts, then the shift acts freely on
the non-identity elements of the group presented. For cyclic presentations defined by
positive words of length at most three, the shift defines a free action if and only if
the presentation is combinatorially aspherical and the shift itself is fixed point free if
and only if the group presented is infinite.

Manogue, Corinne A.; Copeland, Ed; Dray, Tevian
Anderson and DeWitt considered the quantization of a massless scalar field in a spacetime whose spacelike hypersurfaces change topology and concluded that the topology change gives rise to infinite particle and energy production. We show here that their calculations are insufficient and that their propagation rule is unphysical. However, our results using a more general propagation rule support their conclusion.
