摘要:

We define the relative Tits form number W(G, V) of a valued bigraph G at a vertex v and derive some basic properties. We give a detailed analysis of the case when W (G,V) ≥½. The properties of these numbers were used without proof in the classification of Auslander algebras of finite representation type [IPTZ]
