Let D(Ξ›) be the double Ringel-Hall algebra of a finite dimensional hereditary algebra Ξ›. The present paper shows that the BGP-reflection operators of D(Ξ›) coincide with Lusztig's symmetries (up to canonical isomorphisms) and satisfy the braid group relations on the whole double Ringel-Hall algebra D

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

## Abstract For a graph __G__, let __t__(__G__) denote the maximum number of vertices in an induced subgraph of __G__that is a tree. Further, for a vertex __v__∈__V__(__G__), let __t__(__G, v__) denote the maximum number of vertices in an induced subgraph of __G__that is a tree, with the extra cond
