Abstract
The bosonic su(n) Hubbard model was recently introduced. The model was shown to be integrable in one dimension by exhibiting the infinite se t of conserved quantities. I derive the R-matrix and use it to show th at the conserved charges commute among themselves. This new matrix is a nonadditive solution of the Yang-Baxter equation. Some properties of this matrix are derived.
