Title: Quantification des courants de bords et du drift de Lorentz dans
l'effet Hall quantique

Abstract: For a Magnetic Hamiltonian on a half-plane given as the sum
of the Landau Operator with Dirichlet boundary conditions and a random
potential, a quantization theorem for the edge current is proven. This
shows that the concept of edge channels also makes sense in presence
of disorder. Moreover, Gaussian bounds on the heat kernel and its
covariant derivatives are obtained.
