Extriangulated category

WebJun 27, 2024 · Of course, there are extriangulated categories which are neither exact categories nor triangulated categories, see [ 12, 13 ]. Since extriangulated categories generalize both triangulated and exact categories, so one may ask if we can do a similar job on extriangulated categories. WebDec 1, 2024 · A recollement of extriangulated categories is defined in [18] as a diagram of functors between extriangulated categories of the following shape satisfying some …

WebMar 15, 2024 · Then each coheart can be naturally regarded as an extriangulated category. In this setting, if x 1 and x 2 are s-cotorsion pairs (see Definition 3.1(2)), then we have the first main theorem of this paper. Theorem 1.1 Theorem 3.6. Let C be an extriangulated category and x 1, x 2 s-cotorsion pairs. WebWe initiate the study of derived functors in the setting of extriangulated categories.

WebDec 18, 2014 · We define model structures on a triangulated category with respect to some proper classes of triangles and give a general study of triangulated model structures. We look at the relationship between these model structures and cotorsion pairs with respect to a proper class of triangles on the triangulated category. WebExtriangulated categories give a simultaneous generalization of triangulated cate- gories and exact categories. In this paper, we study silting subcategories of an extriangulated category. First, we show that a silting subcategory induces a basis of the Grothendieck group of an extriangulated category. the bridal planner phuket
