    Abstract:

    Let k be a finite fi eld and A be an essentially small hereditary Abelian category over k satisfying some fi niteness conditions.This paper considers the structure constants of the products of complexes with zero di fferentials in MH(A) and show that it is related to the Hall number of the Ringel-Hall algebras H(A).
