Recollements of derived categories II: Algebraic K-theory
Hongxing Chen, Changchang Xi
For a recollement of derived module categories of rings, we provide sufficient conditions to guarantee the additivity formula of higher algebraic K-groups of the rings involved, an…
Algebraic K-theory of endomorphism rings
Hongxing Chen, Changchang Xi
We establish formulas for computation of the higher algebraic -groups of the endomorphism rings of objects linked by a morphism in an additive category. Let be an…
Ringel modules and homological subcategories
Hongxing Chen, Changchang Xi
Given a good -tilting module over a ring , let be the endomorphism ring of , it is an open question whether the kernel of the left-derived functor …
Recollements of derived categories I: Exact contexts
Hongxing Chen, Changchang Xi
Recollements were introduced originally by Beilinson, Bernstein and Deligne to study the derived categories of perverse sheaves, and nowadays become very powerful in understanding…
