Abstract
A ring Î is said to be coherent when the category of finitely presented Î-modules is abelian; otherwise it is said to be incoherent. We show that if G is a group which contains a direct product of nonabelian free groups then the integral group ring Z[G] satisfies a strong form of incoherence, the infinite kernel property.
