 | | The noncommutative space has an arithmetic structure provided by a rational subalgebra closely related to the modular Hecke algebra. |
 | | It acts on values of the ground states at the rational elements via the Galois group of the modular field. |
 | | The action of the symmetry group involves the formalism of superselection sectors and the full noncommutative system at positive temperature. |
