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. optic ghosty twitterWebBULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY S 0273-0979(2013)01417-4 Article electronically published on June 10, 2013 CLUSTER ALGEBRAS: AN INTRODUCTION porthole glassWeb4.2 Grassmannian description of kinematical data—λ and ˜λ 40 4.3 Grassmannian representation of on-shell diagrams 41 ... 16.2 Cluster algebras: seeds, mutations, and cluster coordinates 146 16.3 Cluster amalgamation 150 16.4 (Brief) overview of cluster structures in physics 152 porthole framingWebWeb bases in the sl2 and sl3 cases are important in cluster algebra structure of Grassmannian coordinate rings [FP16, Fra20].
