Baxterizationsolved by Onsager in 1944. A state of the system is defined by a configuration of + and − signs (spins) at the vertices of a square lattice in the plane. Each edge of the lattice is to be thought of as an interaction and contributes an energy E(.) to the total energy where . are the spins at the ends of the edge.

Integrability Off Criticality and Quantum Integrable Systemstensor. For minimal conformal models, there are three distinguished relevant degenerate scalar fields and it turns out that the perturbation with one of these fields preserves one infinite family of conserved commuting integrals. The relation with Toda systems and the supersymmetric extension are briefly discussed.
