Generator Histories and Parity-Odd Curvature in Lorentzian Topology Change
Keith Andrew, Eric V. Steinfelds, Kristopher A. Andrew
Lorentzian topology change may be resolved into an ordered sequence of localized, orientation-sensitive operations rather than treated solely as a global transition between spatial…

Interpolated Topology Change in a Spin Cobordism and the Chiral Weyl Curvature Diagnostic
Keith Andrew, Eric V. Steinfelds, Kristopher A. Andrew
Topology change in Lorentzian quantum gravity demands geometric regulators that control curvature, spin structure, and chirality during nontrivial interpolations. We develop a fram…
