# Relation between solutions to Yang-Baxter equations, integrability and exact solvability?

Wikipedia mentions that there is an implication: Yang-Baxter solutions yield integrable models, what 1D systems concerns.

In arbitrary dimensions, what is the relation, if any, between solutions to Yang-Baxter equations, integrability and exact solvability?

If somebody could provide a no-go theorem or cases, where integrability was already ruled out, it would be great.

Very roughly, the presence of an R-matrix (a solution of the YBE) provides a mechanism for constructing sufficiently many (infinitely many for field-theoretic models) integrals of motion, and this ensures integrability.

As for the YBE in statistical physics, there is a classical book

R.J. Baxter, Exactly solved models in statistical mechanics.

The question was primarily about the higher-dimensional case. Do you have something to add there?
