Query: A Single Slice 2d Anderson Model at Weak Disorder   We introduce a matrix-operator formulation of the Anderson model in d=2. In a
single slice, we can then derive an analogy between our model and a standard
random matrices problem. This enables us to construct and control the Green
function in one slice, which is an important prerequisite to a full multi-scale
study of the problem using the Renormalisation Group approach.
