Photon Scattering by an Electric Field in Noncommutative Spacetime
Daniela D'Ascanio, Pablo Pisani, Ulises Wainstein Haimovichi
As is known, the existence of a small noncommutativity between coordinates would generate nonlocal self-interactions in the electromagnetic theory. To explore some consequences of…
Symmetric affine surfaces with torsion
Daniela D'Ascanio, Peter Gilkey, Pablo Pisani
We study symmetric affine surfaces which have non-vanishing torsion tensor. We give a complete classification of the local geometries possible if the torsion is assumed parallel. T…
Affine Killing vector fields on homogeneous surfaces with torsion
Daniela D'Ascanio, Peter Gilkey, Pablo Pisani
Many extensions of General Relativity are based on considering metric and affine structures as independent properties of spacetime. This leads to the possibility of introducing tor…
Quantum Field Theory on spherical space forms
Daniela D'Ascanio
One of the fundamental questions in Quantum Field Theory regards the determination of a measure of the degrees of freedom of theories that is consistent with the Renormalization Gr…
The geometry of locally symmetric affine surfaces
D. D'Ascanio, P. Gilkey, P. Pisani
We examine the local geometry of affine surfaces which are locally symmetric. There are 6 non-isomorphic local geometries. We realize these examples as Type A, Type B, and Type C g…
Searching for a -function on the three-dimensional sphere
C. G. Beneventano, I. Cavero-Peláez, D. D'Ascanio +1
We present a detailed analytic study on the three-dimensional sphere of the most popular candidates for -functions, both for Dirac and scalar free massive fields. We discuss to…
