Kaluza-Klein ansatz from Lorentzian quantum gravity on the fuzzy sphere
Chengcheng Liu, Shahn Majid
If Kaluza-Klein ideas were correct as an explanation of Yang-Mills and General Relativity on spacetime, the extra fibre geometry would have to be a sphere of constant size of the o…

Fermions in the fuzzy sphere Kaluza-Klein model
Chengcheng Liu, Shahn Majid
We consider spinors on the total space of a Kaluza-Klein model with fuzzy sphere fibre and geometrically realised Dirac operator on the product. We show that a single massless spin…
