Abstract

The module cancellation problem asks whether, given modules X, X0 and Y over a ring Λ, the existence of an isomorphism X ⊕ Y ∼= X0 ⊕ Y implies that X ∼= X0. When q is prime we prove a strong cancellation property for certain modules over Z[C∞×Cq], generalizing, in part, the strong cancellation property for modules over Z[Cq] established in the paper of R.Wiegand [18].
