用范畴的张量积构造对偶范畴

A construction of dualizing categories by tensor products of categories

Yang Han, Ningmei Zhang

摘要:

证明了局部有限模可容许理想的路范畴的剩余范畴的张量积的加性壳与对偶范畴的幂等完备化是对偶的.并且证明了这种张量积范畴上的拟表示函子范畴是对偶的,并且具有几乎可裂序列。作为应用,证明了各种复形的范畴都有几乎可裂序列。

英文摘要:

It is shown that the idempotent completion of the additive hull of the tensor product of the residue category of the category of paths of a locally finite quiver modulo an admissible ideal and a dualizing category is dualizing. Furthermore, the category of finitely presented functors over such tensor product category is dualizing and has almost split sequences. As applications, the categories of all kinds of complexes are proved to have almost split sequences.
