A Scale-Dependent Distance Functional between Past Light Cones in Cosmology
Mauro Carfora, Francesca Familiari
We discuss a rigorous procedure for quantifying the difference between our past lightcone and the past lightcone of the fiducial Friedmann-Lemaitre-Robertson-Walker spacetime model…
A comparison theorem for cosmological lightcones
Mauro Carfora, Francesca Familiari
Let denote a cosmological spacetime describing the evolution of a universe which is isotropic and homogeneous on large scales, but highly inhomogeneous on smaller scales.…
Ricci curvature and quantum geometry
Mauro Carfora, Francesca Familiari
We describe a few elementary aspects of the circle of ideas associated with a quantum field theory (QFT) approach to Riemannian Geometry, a theme related to how Riemannian structur…
Ricci Flow from the Renormalization of Nonlinear Sigma Models in the Framework of Euclidean Algebraic Quantum Field Theory
Mauro Carfora, Claudio Dappiaggi, Nicolò Drago +1
The perturbative approach to nonlinear Sigma models and the associated renormalization group flow are discussed within the framework of Euclidean algebraic quantum field theory and…
Scaling and Entropy for the RG-2 Flow
Mauro Carfora, Christine Guenther
Let be a closed Riemannian manifold. The to the perturbative renormalization group flow for the nonlinear sigma model (RG-2…
The Wasserstein geometry of non-linear sigma models and the Hamilton-Perelman Ricci flow
Mauro Carfora
Non linear sigma models are quantum field theories describing, in the large deviations sense, random fluctuations of harmonic maps between a Riemann surface and a Riemannian manifo…
