Let K be a fixed field. We attach to each column-finite quiver E a von Neumann regular K-algebra Q (E) in a functorial way. The algebra Q (E) is a universal localization of the usual path algebra P (E) associated with E. The monoid of isomorphism classes of finitely generated projective right Q (E)-modules is explicitly computed. © 2006 Elsevier Inc. All rights reserved.
