由带势箭图的突变导出的等价性

Derived equivalences from mutations of quivers with potential

Bernhard Keller, Dong Yang

摘要:

我们表明,Derksen-Weyman-Zelevinsky突变的箭与潜在的产量等价的合适的3-Calabi-Yau三角范畴。我们的方法与Iyama-Reiten和Koszul的方法有关,与Kontsevich-Soibelman的方法有关。它改进了维多利亚以前的工作。在附录中,第一作者研究了某些伪紧dg代数的伪紧导出范畴。

英文摘要:

We show that Derksen-Weyman-Zelevinsky's mutations of quivers with potential yield equivalences of suitable 3-Calabi-Yau triangulated categories. Our approach is related to that of Iyama-Reiten and Koszul dual to that of Kontsevich-Soibelman. It improves on previous work by Vitoria. In the appendix, the first-named author studies pseudo-compact derived categories of certain pseudo-compact dg algebras.
