Algebraic study of quantum configuration spaces of decorated flags

Tsukasa Ishibashi, Hironori Oya

Let $G$ be a connected, simply connected complex simple algebraic group and $A_{G} = G / U^{+}$ its base affine space, whose elements are called decorated flags. We introduce the…

Unbounded $sl_{3}$ -laminations around punctures

Tsukasa Ishibashi, Shunsuke Kano

We continue to study the unbounded $sl_{3}$ -laminations [IK22], with a focus on their structures at punctures. A key ingredient is their relation to the root data of $\mat…

Entropy of cluster DT transformations and the finite-tame-wild trichotomy of acyclic quivers

Tsukasa Ishibashi, Shunsuke Kano

The cluster algebra associated with an acyclic quiver has a special mutation loop $τ$ , called the cluster Donaldson--Thomas (DT) transformation, related to the Auslander--Reiten tr…
