Query: A new classification scheme for Random Matrix Theories   In the last few years several new Random Matrix Models have been proposed and
studied. They have found application in various different contexts, ranging
from the physics of mesoscopic systems to the chiral transition in lattice
gauge theory. These new ensembles can be classified in terms of the same Dynkin
diagrams and root lattices which are used in the classification of the Lie
algebras.
