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. WebOn the other hand, not all triangulated subcategories of the bounded derived category of a smooth projective variety admit Serre-invariant stability conditions. In the recent paper [ 22 ], the authors show that the Kuznetsov component (called residual category) of almost all Fano complete intersections of codimension ≥2 does not admit Serre ...

Number 1 gives both 2 and 3. 2 or 3 do not give each other or 1. Each of these gadgets gives you a realization of your category as derived representations of a directed quiver (with relations),
