报告摘要:
In this talk, I will introduce the notion of right pre-resolutions (quasi-resolutions) for a right noetherian graded algebra A with finite right injective dimension, which is a weaker version of quasi-resolutions introduced by Qin-Wang-Zhang. As I will show, two quasi-resolutions of A are always Morita equivalent in the case of dimension 2. We will make further discussion on AS-Gorenstein singularities, and show an explicit construction of pre-resolutions of a noncommutative quadric hypersurface with isolated singularities. This is based on a joint work with Jiwei He.
