As a continuation of the work of Ringel and Green on Hall algebras, the Hopf Ε½ . 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
