Recollements of Cohen-Macaulay Auslander algebras and Gorenstein derived categories
Javad Asadollahi, Rasool Hafezi, Razieh Vahed
Let , and be associative rings with identity. Using a result of Koenig we show that if we have a $\mathbb{D}^{\rm{b}}({\rm{mod\mbox{-}}} )$ level recollement, writing $A…
