Constraining the Noncommutative Spectral Action via Astrophysical Observations
Constraining the Noncommutative Spectral Action via Astrophysical Observations
The noncommutative spectral action extends our familiar notion of commutative spaces, using the data encoded in a spectral triple on an almost commutative space. Varying a rather simple action, one can derive all of the standard model of particle physics in this setting, in addition to a modified version of …
