论相对刚度与支架倾斜的关系

On the relation between relative rigid and support tilting

Yu Liu, Panyue Zhou

摘要:

设B是一个具有足够投射和足够内射的外三角范畴。设C是B的一个完全刚性子范畴,它允许一个双余挠对((C,K),(K,D))。商范畴B/K是阿贝尔范畴,我们假设它是遗传的,有有限长.本文研究了B/K的支撑倾斜子范畴与B的极大相对刚性子范畴之间的关系。更精确地说,我们证明了B的任何簇倾斜子范畴在B/K中的象都是支撑倾斜的,并且B/K中的任何支撑倾斜子范畴都可以提升到B中唯一的相对极大刚性子范畴.如果C是由一个对象生成的,我们也给出了这两类子范畴之间的一个双射。

英文摘要:

Let B be an extriangulated category with enough projectives and enough injectives. Let C be a fully rigid subcategory of B which admits a twin cotorsion pair ((C,K),(K,D)). The quotient category B/K is abelian, we assume that it is hereditary and has finite length. In this article, we study the relation between support tilting subcategories of B/K and maximal relative rigid subcategories of B. More precisely, we show that the image of any cluster tilting subcategory of B is support tilting in B/K and any support tilting subcategory in B/K can be lifted to a unique relative maximal rigid subcategory in B. We also give a bijection between these two classes of subcategories if C is generated by an object.
