報告題目:Tilting-completion, $\tau_n$-finiteness and n-completeness for gentle algebras

報告時間：2024年7月24日下午3：00-4：00

報告地點：理工樓518

摘要：The purpose of this talk is two-fold. Firstly, we study the self-orthogonal modules over a gentle algebra. In particular, it is proved that any almost tilting module over a gentle algebra is partial tilting. At the same time, for any n > 2 and 0 < m < n-2, there always exists a gentle with rank n and a pre-tilting module over it with rank m which is not partial tilting. Secondly, we give a complete classification of gentle algebras that are $\tau_n$-finite, and n-complete with respect to a tilting module in the sense of Iyama. The tool we use is the geometric model of the module category over a gentle algebra.
