Cluster characters for 2-Calabi-Yau Frobenius extriangulated categories

Li Wang, Jiaqun Wei, Haicheng Zhang

We define the cluster characters for 2-Calabi-Yau Frobenius extriangulated categories with cluster tilting objects. This provides a unified framework of cluster characters in 2-Cal…

A Note on Odd Periodic derived Hall algebras

Haicheng Zhang, Xinran Zhang, Zhiwei Zhu

Let $m$ be an odd positive integer and $D_{m} (A)$ be the $m$ -periodic derived category of a finitary hereditary abelian category $A$ . In this note, we prove tha…

Periodic derived Hall algebras of hereditary abelian categories

Haicheng Zhang

Let $m$ be a positive integer and $D_{m} (A)$ be the $m$ -periodic derived category of a finitary hereditary abelian category $A$ . Applying the derived Hall numbe…
