| Abstract: | A relation between the additive functions on graphs and the representation theory of hereditary algebras was established, and the structure of trees with non-zero additive functions was characterized.Furthermore, the relation between the radical of path algebras and the structure of its Gabriel quivers were constructed.As an application, the existence of path algebras with the arbitrary corank was constructed. |
