... of the su(2) symmetry. Since the su(2) fusion rule is (1/2)⊗(1/2) = (0)+(1), these states can be grouped into the s = 1 triplet representation and the s = 0 singlet representation, as defined in (3.7) and (3.8). It is simple to check that S~ · S~ = s(s + 1) in the two cases, ~ acting with S + and a ...

More precisely, the fact that the quantization of the Hall conductance appears as a very robust phenomenon, insensitive to changes in the sample and its geometry, or to the presence of impurities, suggests the fact that the ...
