Cluster structures on
Jeff York Ye
The paper constructs cluster algebra structures on the strata of the symmetric space SL_n/SO_n by folding upper cluster algebras from SL_n, and shows these structures are compatibl…

Reductive monoids and cluster algebras
Jinfeng Song, Jeff York Ye
We show that the coordinate ring of the Vinberg monoid of a simply connected semisimple complex group is an upper cluster algebra. As an application, we construct cluster structure…

Upper cluster structure on Kac--Moody Richardson varieties
Huanchen Bao, Jeff York Ye
We show coordinate rings of open Richardson varieties are upper cluster algebras for any symmetrizable Kac--Moody type. We further show the coordinate rings of (generalized) open R…
