Noncommutative standard model
In theoretical particle physics, the non-commutative Standard Model (best known as Spectral Standard Model), is a model based on noncommutative geometry that unifies a modified form of general relativity with the Standard Model (extended with right-handed neutrinos). The model postulates that space-time is the product of a 4-dimensional compact spin manifold M {\displaystyle {\mathcal {M}}} by a finite space F {\displaystyle {\mathcal {F}}} .
