Igusa-Todorov properties of recollements of abelian categories
Peiru Yang, Yajun Ma, Yu-Zhe Liu
In this paper, we investigate the behavior of Igusa-Todorov properties under recollements of abelian categories. In particular, we study how the Igusa-Todorov distances of the cate…

Three homological invariants under cleft extensions
Yajun Ma, Junling Zheng, Yu-Zhe Liu
In this paper, we investigate the behavior of Igusa-Todorov distances, extension and Rouquier dimensions under cleft extensions of abelian categories. We apply our results to Morit…
