报告摘要：In this talk, we investigate the annihilator of the singularity category, focusing on its connection to the finiteness of the Rouquier dimension and the nonvanishing of the annihilator of the singularity category. Notably, for the Gorenstein local ring, we observe interesting properties of its representation theory when the annihilator coincides with the maximal ideal. This talk is based on the joint work with Souvik Dey, Yuki Mifune, and Yuya Otake.
