WebWhat do cluster algebras tell us about Grassmannians? One of the first examples of a cluster algebra given in Fomin and Zelevinsky's original paper is the homogeneous coordinate ring C [ G 2, n] of the Grassmannian of planes in C n. It has also been shown by Scott that C [ G k, n] carries a cluster algebra structure for any k. WebWeb bases in the sl2 and sl3 cases are important in cluster algebra structure of Grassmannian coordinate rings [FP16, Fra20].
