我们研究科恩和斯科菲尔德意义上的有限维代数的普遍定位,并根据我们初始模块类别的某些子类别对它们进行分类。在遗传案例以及中山代数和局部代数中给出了完整的分类。此外,对于遗传代数,我们在有限维通用定位和有限生成的支撑倾斜模块之间建立了对应关系。在中山案例中,我们使用 τ 倾斜模块得到了类似的结果,该模块最近由 Adachi、Iyama 和 Reiten 引入。
We study universal localisations, in the sense of Cohn and Schofield, for finite dimensional algebras and classify them by certain subcategories of our initial module category. A complete classification is presented in the hereditary case as well as for Nakayama algebras and local algebras. Furthermore, for hereditary algebras, we establish a correspondence between finite dimensional universal localisations and finitely generated support tilting modules. In the Nakayama case, we get a similar result usingτ-tilting modules, which were recently introduced by Adachi, Iyama and Reiten.
