Equivalence principle in statistical mechanics
We introduce the notion of equivalence of models of statistical mechanics which is stronger than the ``weak equivalence'' widely discussed in the literature. We show that any ``generalized interaction round-a-face'' model is equivalent to a spin model and to a vertex model. It implies, in particular, that for any spin model there is an equivalent vertex model.
