AFFINE SEMIGROUPS HAVING A UNIQUE BETTI ELEMENT

    https://doi.org/10.1142/S0219498812501770Cited by:21 (Source: Crossref)

    We characterize affine semigroups having one Betti element and we compute some relevant non-unique factorization invariants for these semigroups. As an example, we particularize our description to numerical semigroups.
