When data seems to be gathered around a particular value. For example: for the values 2, 6, 7, 8, 8.5, 10, 15, there is a cluster around the value 8. See: Outlier.
Cluster algebras are a class of commutative rings introduced by Fomin and Zelevinsky (2002, 2003, 2007). A cluster algebra of rank n is an integral domain A, together with some subsets of size n called clusters whose union generates the algebra A and which satisfy various conditions.luster algebras of rank 2 [edit]. Suppose that we start with the cluster { x 1, x 2 } and take the exchange matrix with b 12 =âb 21 =1. Then mutation gives a sequence of variables x 1, x 2, x 3, x 4 ,... such that the clusters are given by adjacent pairs { x n, x n+1 }.
