Abstract
A review of the recent formulation of the quantum discrete Liouville model in the strongly coupled regime (corresponding to the Virasoro central charge 1<c<25) is presented. The Q-operator, describing the integrable structure of the model and satisfying a pair of dual Baxter equations, is obtained as a certain non-homogeneous transfer-matrix associated with the six-vertex model.
