Crystal Structure of Upper Cluster Algebras
Jiarui Fei
We describe the upper seminormal crystal structure for the -supported -vectors for any quiver with potential with reachable frozen vertices, or equivalently for the tropical…

On the General Ranks of QP Representations
Jiarui Fei
We propose a mutation formula for the general rank from a principal component of representations to another one for a quiver with potential. We give suf…
