New Developments in the Spectral Asymptotics of Quantum Gravity
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
A vanishing one-loop wave function of the Universe in the limit of small three-geometry is found, on imposing diffeomorphism-invariant boundary conditions on the Euclidean 4-ball i…
A Non-Singular One-Loop Wave Function of the Universe From a New Eigenvalue Asymptotics in Quantum Gravity
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
Recent work on Euclidean quantum gravity on the four-ball has proved regularity at the origin of the generalized zeta-function built from eigenvalues for metric and ghost modes, wh…
A New Spectral Cancellation in Quantum Gravity
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
A general method exists for studying Abelian and non-Abelian gauge theories, as well as Euclidean quantum gravity, at one-loop level on manifolds with boundary. In the latter case,…
Spectral asymptotics of Euclidean quantum gravity with diff-invariant boundary conditions
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
A general method is known to exist for studying Abelian and non-Abelian gauge theories, as well as Euclidean quantum gravity, at one-loop level on manifolds with boundary. In the l…
