Let H H kQ be the Ringel᎐Hall algebra of affine quiver Q. All indecomposable Ž . representations of Q, which can be generated inside H H kQ by ''smaller'' represen-Ž . tations of Q, are classified; systems of minimal homogeneous generators of H H kQ are explicitly written out.
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
