Noncommutative geometrical origin of the energy-momentum dispersion relation
Apimook Watcharangkool, Mairi Sakellariadou
We investigate a link between the energy-momentum dispersion relation and the spectral distance in the context of a Lorentzian almost-commutative spectral geometry, defined by the…

Linear stability of noncommutative spectral geometry
Mairi Sakellariadou, Apimook Watcharangkool
We consider the spectral action within the context of a 4-dimensional manifold with torsion and show that, in the vacuum case, the equations of motion reduce to Einstein's equation…
