Résumé : The talk is focused on some particular family of statistical models on 6-valent graphs and their relations with the theory of invariants of 2-knots, i.e. the isotopy classes of S2 embeddings in R4, and integrable 3-d models of statistical physics on regular latices. In both cases the integrability properties are provided by the higher homotopic algebraic structure related with the Zamolodchikov tetrahedron equation.
