On Symmetric Numerical Semigroups
A numerical semigroup is a subset S of N such that is closed under sums, contains the zero and generates Z as a group. From this definition Ž w x. Ž one obtains see, for example, 2 that S has a conductor C i.e., the . maximum among all the natural numbers not belonging to S . A numerical semigroup S is called symmetric if for every integer z f S, C y z g S. The study of the subsemigroups of N i...
متن کاملAlmost Symmetric Numerical Semigroups Generated by Four Elements
In this paper, we study almost symmetric numerical semigroups generated by 4-elements. Rosales and Garćıa-Sánchez [RG2] proved that every almost symmetric numerical semigroup can be constructed by removing some minimal generators from an irreducible numerical semigroup with the same Frobenius number. Using this result, we concretely construct almost symmetric numerical semigroups generated by 4...
متن کاملSymmetric Numerical Semigroups Generated by Fibonacci and Lucas Triples
The symmetric numerical semigroups S (Fa, Fb, Fc) and S (Lk, Lm, Ln) generated by three Fibonacci (Fa, Fb, Fc) and Lucas (Lk, Lm, Ln) numbers are considered. Based on divisibility properties of the Fibonacci and Lucas numbers we establish necessary and sufficient conditions for both semigroups to be symmetric and calculate their Hilbert generating series, Frobenius numbers and genera.
متن کاملSymmetric Numerical Semigroups with Arbitrary Multiplicity and Embedding Dimension
We construct symmetric numerical semigroups S for every minimal number of generators μ(S) and multiplicity m(S), 2 ≤ μ(S) ≤ m(S) − 1. Furthermore we show that the set of their defining congruence is minimally generated by μ(S)(μ(S) − 1)/2 − 1 elements.
متن کاملRemarks on Numerical Semigroups
We extend results on Weierstrass semigroups at ramified points of double covering of curves to any numerical semigroup whose genus is large enough. As an application we strengthen the properties concerning Weierstrass weights stated in [To]. 0. Introduction Let H be a numerical semigroup, that is, a subsemigroup of (N,+) whose complement is finite. Examples of such semigroups are the Weierstras...
