Weyl Symmetry in Stochastic Quantum Gravity
Laurent Baulieu, Luca Ciambelli, Siye Wu
We propose that the gauge principle of d-dimensional Euclidean quantum gravity is Weyl invariance in its stochastic (d+1)-dimensional bulk. Observables are defined as depending onl…
Carroll Structures, Null Geometry and Conformal Isometries
Luca Ciambelli, Robert G. Leigh, Charles Marteau +1
We study the concept of Carrollian spacetime starting from its underlying fiber-bundle structure. The latter admits an Ehresmann connection, which enables a natural separation of t…
Weyl Connections and their Role in Holography
Luca Ciambelli, Robert G. Leigh
It is a well-known property of holographic theories that diffeomorphism invariance in the bulk space-time implies Weyl invariance of the dual holographic field theory in the sense…
