Popis: Let R be a hereditary Noetherian prime ring. We determine a full set of invariants for the isomorphism class of any finitely generated projective R -module of uniform dimension at least 2. In particular we prove that P ⊕ X ≅ Q ⊕ X implies P ≅ Q whenever P has uniform dimension at least 2. Among the applications of these results are necessary and sufficient conditions for the existence of a bound to the number of generators needed for right ideals of R .
