摘要：
In analogy with the Liouville case we study the sl(3) Toda theory on the lattice and define the relevant quadratic algebra and out of it we recover the discrete W-3 algebra. We define an integrable system with respect to the latter and establish the relation with the Toda lattice hierarchy. We compute the relevant continuum limits. Finally we find the quantum version of the quadratic algebra.
