本文研究了重坍中三个三角范畴之间的余挠对关系。证明了如果一个三角化范畴<$1含有一个相对于三角化范畴<$′和<$″的互元,则可以由<$′和<$″中的余挠对得到<$1中的余挠对。𝒟另一方面,我们证明了在π中的某些余挠对可以诱导π′和π″中的余挠对。此外,我们还从三角范畴的重元构造了阿贝尔范畴的重元。
In the present article, we study the relationship of cotorsion pairs among three triangulated categories in a recollement. We show that if a triangulated category 𝒟 admits a recollement relative to triangulated categories 𝒟′ and 𝒟″, we can obtain cotorsion pairs in 𝒟 from cotorsion pairs in 𝒟′ and 𝒟″. On the other hand, we prove that certain cotorsion pairs in 𝒟 can induce cotorsion pairs in 𝒟′ and 𝒟″. Furthermore, we construct recollements of abelian categories from a recollement of triangulated categories.
