Abstract
Let R be a commutative noetherian ring and A a noetherian R-algebra. Let P • ∈ 𝒦b(𝒫 A ) with Hom𝒦(Mod-A)(P •, P •[i]) = 0 for i > 0. We will provide a sufficient condition for P • to be a direct summand of a silting complex. Also, in case Hom𝒦(Mod-A)(P •, P •[i]) = 0 for i ≠ 0, we will provide a sufficient condition for P • to be a direct summand of a tilting complex.
