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is an important prerequisite to a full multi-scale study of the problem using the Renormalisation Group approach.paper withdrawn, reader can refer to cond-mat/9702111 for a stronger result with a much understandable derivation along with various bug fixingDisordered Systems and Neural Networkstext
