Abstract
Transitions between the quantum Hall state and the Anderson insulator are s tudied in a two-dimensional tight-binding model with a uniform magnetic fie ld and a random potential. Focus is put on a weak magnetic-held regime. It is closely related to the continuum model. By applying topological argument s and the Thouless-number study, the Nay how the Hall conductance changes i s elucidated and light is shed on the trajectory of the delocalized states.
