Wick Rotation and Fermion Doubling in Noncommutative Geometry
Francesco D'Andrea, Maxim A. Kurkov, Fedele Lizzi
In this paper, we discuss two features of the noncommmutative geometry and spectral action approach to the Standard Model: the fact that the model is inherently Euclidean, and that…
The spectral distance on the Moyal plane
Eric Cagnache, Francesco D'Andrea, Pierre Martinetti +1
We study the noncommutative geometry of the Moyal plane from a metric point of view. Starting from a non compact spectral triple based on the Moyal deformation A of the algebra of…
Spectral geometry of -Minkowski space
Francesco D'Andrea
After recalling Snyder's idea of using vector fields over a smooth manifold as `coordinates on a noncommutative space', we discuss a two dimensional toy-model whose `dual' noncommu…
Action functional for kappa-Minkowski Noncommutative Spacetime
Alessandra Agostini, Giovanni Amelino-Camelia, Michele Arzano +1
We examine some alternative possibilities for an action functional for -Minkowski noncommutative spacetime, with an approach which should be applicable to other spacetimes with…
Group velocity in noncommutative spacetime
Giovanni Amelino-Camelia, Francesco D'Andrea, Gianluca Mandanici
The realization that forthcoming experimental studies, such as the ones planned for the GLAST space telescope, will be sensitive to Planck-scale deviations from Lorentz symmetry ha…
Comparison of relativity theories with observer-independent scales of both velocity and length/mass
Giovanni Amelino-Camelia, Dario Benedetti, Francesco D'Andrea +1
We consider the two most studied proposals of relativity theories with observer-independent scales of both velocity and length/mass: the one discussed by Amelino-Camelia as illustr…
