摘要
The bocs corresponding to each hereditary algebra of representation tame type is shown. And the minimal bocs obtained from it is given with only irreducible maps for each dimension d. The minimal bocs (after deleting finitely many vertices) coincides with a full subquiver of the AR-quiver of hereditary algebra, in which the indecomposable modules M have the property dim (top M)<d.
