Grassmannian cluster algebras
WebMay 23, 2014 · 1. Introduction. Since cluster algebras were introduced by Fomin and Zelevinsky [], it has been recognized that cluster algebra structures on homogeneous coordinate rings on Grassmannians are among the most important classes of examples.The demonstration of the existence of such a structure is due to Scott [] and one reason for … Webproves that the upper cluster algebra structure on Ge,w 0 given in [2]isinfactacluster algebra structure. Section 3 is devoted to recall basic definitions from the theory of cluster algebras. In particular we recall the (upper) cluster algebra structure on Ge,w 0 as given in [2]. In Section 4 we explain how to get the initial seeds for A i ...

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, … Web求真书院举行2024级数学领军计划预科班学生与益友学者见面会 求真书院. 为保障每位求真学子收获最大幅度的成长，求真书院聘请了来自清华大学丘成桐数学科学中心（ymsc）和北京雁栖湖应用数学研究院（bimsa）的优秀博士后担任求真益友学者。
