摘要

为了研究簇倾斜代数及其中间覆盖,Zhu引入了重复型簇类的概念,定义为轨道范畴mathcalDb(mathcalH)/langle(tau1Sigma)prangle\\mathcal D^b(\\mathcal H)/\\langle(\\tau^{-1}\\Sigma)^p\\rangle,其中1leqpinmathbbN1\\leq p\\in\\mathbb{N}mathcalH\\mathcal H是具有倾斜对象的可换本征范畴。本文计算了重复型簇范畴mathcalDb(rmmodKAn)/langle(tau1Sigma)prangle\\mathcal D^b({\\rm mod}KA_n)/\\langle(\\tau^{-1}\\Sigma)^p\\ranglemathcalDb(rmmodKDn)/langle(tau1Sigma)prangle\\mathcal D^b({\\rm mod} KD_n)/\\langle(\\tau^{-1}\\Sigma)^p\\rangle的Grothendieck群的部分但关键结果。我们的结果扩展了经典簇范畴的已知计算,揭示了重复参数p\\ p所引发的新结构模式,并为Grothendieck群、阿尔斯坦-赖特尔-瑞坦理论与 Coxeter 变换之间的紧密相互作用提供了进一步的证据。
