Description

We review the Johnson-Moser rotation number and the K0-theoretical gap labelling of Bellissard for one-dimensional Schroedinger operators. We compare them with two further gap labels, one being related to the motion of Dirichlet eigenvalues, the other being a K1-theoretical gap label. We argue that the latter provides a natural generalization of the Johnson-Moser rotation number to higher dimensions
