Derived categories and tilting

WebA tilting complex T over A is an object in Kb(P(A)) which satisfies the following conditions: (I) for all i ≠ 0, the set HomDb(A)(T, T[i]) of homomorphisms in Db(A) vanishes, (II) the category add(T) (that is, the full subcategory of all direct sums of direct summands of T inside Kb(P(A))) generates Kb(P(A)) as a triangulated category. WebJan 1, 2007 · Below we state the well-known tilting correspondence which is a direct application of a more general result on triangulated categories (see [10], Theorem 8.5). …
