• Let A be a finite-dimensional Q -algebra and Γ ⊂ A a Z -order. We classify those A with the property that Z 2 ▪ U ( Γ ) and refer to this as the hyperbolic property. We apply this in case A = K S is a semigroup algebra, with K = Q or K = Q ( − d ) . A complete classification is given when KS is semi-simple and also when S is a non-semi-simple semigroup.
