团簇与经典倾斜的关系

On the relation between cluster and classical tilting

Thorsten Holm, Peter Jorgensen

摘要:

设D是一个三角化范畴,其上有一个簇倾斜子范畴U。商范畴D/U是阿贝尔范畴,设它具有有限的整体维数.我们证明了从D到D/U的投影使D的簇倾斜子范畴成为D/U的支撑倾斜子范畴,并且反过来,D/U的支撑倾斜子范畴可以唯一地提升为D的极大1-正交子范畴.

英文摘要:

Let D be a triangulated category with a cluster tilting subcategory U. The quotient category D/U is abelian; suppose that it has finite global dimension. We show that projection from D to D/U sends cluster tilting subcategories of D to support tilting subcategories of D/U, and that, in turn, support tilting subcategories of D/U can be lifted uniquely to maximal 1-orthogonal subcategories of D.
