我们研究 Dynkin 型原射代数上的倾斜复形。我们通过给出倾斜复合体和相应折叠图的编织群之间的双射来对所有倾斜复合体进行分类。特别是,我们确定代数的派生等价类。针对这一结果,我们发展了淤积离散三角范畴理论,并给出了淤积离散性判据。
We study tilting complexes over preprojective algebras of Dynkin type. We classify all tilting complexes by giving a bijection between tilting complexes and the braid group of the corresponding folded graph. In particular, we determine the derived equivalence class of the algebra. For the results, we develop the theory of silting-discrete triangulated categories and give a criterion of silting-discreteness.
