Classical Signature Change in the Black Hole Topology

  • Charles Hellaby


Investigations of classical signature change have generally envisaged applications to cosmological models, usually a FriedmannLemâıtre-Robertson-Walker model. The purpose has been to avoid the inevitable singularity of models with purely Lorentzian signature, replacing the neighbourhood of the big bang with an initial, singularity free region of Euclidean… (More)
