In these two lectures I describe the difficulties one encounters when trying to construct a framework in which to describe topology change in classical general relativity where one sticks to the assumption of an everywhere non-singular Lorentzian metric and how these difficulties can be circumvented in the Euclidean approach to quantum gravity.

  1. Wormhole Nucleation via Topological Surgery in Lorentzian Geometry

    gr-qc 2025-05 unverdicted novelty 7.0

    Wormhole nucleation is achieved via 0-surgery yielding a singular cobordism, resolved by connected sum with CP² to produce a nonsingular Lorentzian metric with closed timelike curves and violated energy conditions.
