Additive categorification of the monoidal $I^$ -invariant

Ricardo Canesin, Peigen Cao, Geoffrey Janssens

In this paper, we contribute to the broad aim of relating invariants of additive and monoidal categorifications of cluster algebras. Specifically, in the setting of representations…

Newton polytopes in cluster algebras and $I ¨ $ -tilting theory

Peigen Cao

We prove that the cluster monomials in non-initial cluster variables are uniquely determined by the Newton polytopes of their $F$ -polynomials for skew-symmetrizable cluster algebra…

F-invariant and E-invariant

Peigen Cao

$F$ -invariant for a pair of good elements (e.g. cluster monomials) in cluster algebras is introduced by the author in a previous work. A key feature of $F$ -invariant is that it is…

Modules determined by their Newton polytopes

Peigen Cao

In the $I ¨ $ -tilting theory, there exist two classes of foundamental modules: indecomposable $I ¨ $ -rigid modules and left finite bricks. In this paper, we prove the indecomposable $Ï…
