In the Kaluza-Klein theory with fuzzy sphere fiber, I will show how SU(2) Yang-Mills field and a real-symmetric-matrix valued Liouville-sigma model field arise from the dimensional reduction of Ricci scalar. Moreover, with this noncommutative fiber, we can derive the cylinder ansatz in usual KK theory.
Additionally, the KK tower of scalar and spinor field will obtain the natural truncation...

End-of-the-World branes are codimension-one hypersurfaces that mark the ending of spacetime. Interestingly, these have been argued to be necessary ingredients in quantum gravity to prevent the presence of global symmetries. Can they also serve as braneworlds? (Spoiler: Yes.) Motivated by the Swampland Programme and in particular the Cobordism Conjecture, we propose a scenario in which a...
