Introduction This paper follows the … WebLet us first motivate the need for a notion of distance in a cluster algebra, concentrating on the example of the Grassmannian. A pair of Plücker coordinates can appear together in the same cluster if and only if they are labeled by weakly separated subsets of [n] delimited-[] 𝑛 [n] [ italic_n ].For Plücker coordinates that do not appear together in the same cluster, … daktronics twitterWebWhat 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. biotin hyperthyroidism
