DEGENERATING 0 IN TRIANGULATED CATEGORIES

چکیده
In previous work, based on the work of Zwara and Yoshino, we defined studied degenerations objects in triangulated categories analogous to degeneration modules. ${\mathcal{T}}$ , it is surprising that zero object may degenerate. We show subcategory generated by are coincides with consisting a vanishing image Grothendieck group $K_{0}({\mathcal{T}})$ .

Objects in Triangulated Categories
We introduce the Calabi-Yau (CY) objects in a Hom-finite Krull-Schmidt triangulated k-category, and notice that the structure of the minimal, consequently all the CY objects, can be described. The relation between indecomposable CY objects and Auslander-Reiten triangles is provided. Finally we classify all the CY modules of selfinjective Nakayama algebras, determining this way the self-injectiv...
متن کاملLocalizations in Triangulated Categories and Model Categories
Recall that for a triangulated category T , a Bousfield localization is an exact functor L : T → T which is coaugmented (there is a natural transformation Id → L; sometimes L is referred to as a pointed endofunctor) and idempotent (there is a natural isomorphism Lη = ηL : L → LL). The kernel ker(L) is the collection of objects X such that LX = 0. If T is closed under coproducts, it’s a localizi...
متن کاملHeller triangulated categories
Let E be a Frobenius category, let E denote its stable category. The shift functor on E induces a first shift functor on the category of acyclic complexes with entries in E by pointwise application. Shifting a complex by 3 positions yields a second shift functor on this category. Passing to the quotient modulo split acyclic complexes, Heller remarked that these two shift functors become isomorp...
متن کاملStratifying Triangulated Categories
A notion of stratification is introduced for any compactly generated triangulated category T endowed with an action of a graded commutative noetherian ring R. The utility of this notion is demonstrated by establishing diverse consequences which follow when T is stratified by R. Among them are a classification of the localizing subcategories of T in terms of subsets of the set of prime ideals in...
متن کاملOn Triangulated Orbit Categories
We show that the category of orbits of the bounded derived category of a hereditary category under a well-behaved autoequivalence is canonically triangulated. This answers a question by Aslak Buan, Robert Marsh and Idun Reiten which appeared in their study [8] with M. Reineke and G. Todorov of the link between tilting theory and cluster algebras (cf. also [16]) and a question by Hideto Asashiba...
