報告題目：Cluster characters for 2-Calabi-Yau Frobenius extriangulated categories
報告時間：10月1日下午14：00--15:00
報告地點：圖書館1707
摘 要：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-Calabi-Yau triangulated categories and 2-Calabi-Yau Frobenius exact categories given by Palu and Fu--Keller, respectively. This talk is based on the join work with Li Wang, Jiaqun Wei.
