Abstract: |
Within the context of the LLM geometries, I will argue that there is no natural topology measuring operator. Instead, one can change the topology of spacetime by superposing states with fixed topology. I will also explain how generalized uncertainties and entanglement between modes can be computed from first principles and display regular patterns that can be used to measure the topology. |
