Cluster Algebras, Invariant Theory, and Kronecker Coefficients II

Jiarui Fei

We prove that the semi-invariant ring of the standard representation space of the $l$ -flagged $m$ -arrow Kronecker quiver is an upper cluster algebra for any $l, m \in N$ . Th…

Extending Upper Cluster Algebras

Jiarui Fei, Jerzy Weyman

Let $S$ be an upper cluster algebra, which is a subalgebra of $R$ . Suppose that there is some cluster variable $x_{e}$ such that $R_{x_{e}} = S [x_{e}^{\pm 1}]$ . We try to understan…
