This aforementioned sequence of mutations is an important ingredient in showing that the corresponding upper cluster algebra is isomorphic to the ring of regular functions on the space of matrices of size n by m. It has been conjectured that there exists a classification of regular cluster structures on simple complex Lie groups that is parallel to the Belavin-Drinfeld classification of Poisson-Lie Brackets. cache/w6634171p0d.txt txt/w6634171p0d.txt
