As a continuation of the work of Ringel and Green on Hall algebras, the Hopf Ž . algebra structure of a extended twisted Hall algebra is presented here. By introducing the Ringel pairing of Hall algebras, the Drinfeld double of a Hall algebra is constructed. The reduced form of this Drinfeld double

Given a finite dimensional hereditary algebra Λ over a finite field k, in the derived category D b (Λ) we obtain some formulae on Hall numbers associated to triangles. Using them we prove that, for any tilted algebra Γ of Λ, there is an embedding of the twisted Ringel-Hall algebra of Γ into the Drin
