The genus, Frobenius number and pseudo-Frobenius numbers of numerical semigroups of type 2
Published online by Cambridge University Press: 19 July 2016
Extract
We study some questions on numerical semigroups of type 2. On the one hand, we investigate the relation between the genus and the Frobenius number. On the other hand, for two fixed positive integers g1, g2, we give necessary and sufficient conditions in order to have a numerical semigroup S such that {g1, g2} is the set of its pseudo-Frobenius numbers and, moreover, we explicitly build families of such numerical semigroups.
