报告摘要：In this talk, we investigate homological dimensions, including finitistic, big finitistic, and global dimensions, and establish explicit inequalities that relate the dimensions of the middle category in a recollement to those of the outer categories. These results extend classical theorems from ring theory to the broader framework of triangulated categories, providing new tools for analyzing homological invariants in this more general setting. This is based on a joint work with Hongxing Chen and Xiaohu Chen (Capital Normal University).
