We describe the structure of infinitely generated projective modules over hereditary Noetherian prime rings. The isomorphism invariants are uniform dimension and ranks at maximal ideals. Infinitely generated projective modules need not be free. However, every uncountably generated projective module

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 โ X โผ = Q โ X implies P โผ = Q whenever P has uniform dimension at least 2. Among t
We prove that, for every regular ring R, there exists an isomorphism between the monoids of isomorphism classes of finitely generated projective right modules ลฝ ลฝ . . ลฝ . over the rings End R and RCFM R , where the latter denotes the ring of R R countably infinite row-and column-finite matrices over
