Cluster Algebras and Semi-invariant Rings I. Triple Flags
Jiarui Fei
We prove that each semi-invariant ring of the complete triple flag of length is an upper cluster algebra associated to an ice hive quiver. We find a rational polyhedral cone ${…

On Some Quiver Determinantal Varieties
Jiarui Fei
We introduce certain quiver analogue of the determinantal variety. We study the Kempf-Lascoux-Weyman's complex associated to a line bundle on the variety. In the case of generalize…
