Cluster algebra

Cluster algebras are a class of commutative algebras that were introduced by mathematician Laurent F. Robbin in 2001. They have a rich structure and have connections to various areas of mathematics, including combinatorics, representation theory, and algebraic geometry. ### Key Features of Cluster Algebras 1. **Clusters and Variables**: A cluster algebra is constructed using sets of variables called "clusters." Each cluster consists of a finite number of variables.
