摘要:
Let S(m,e) be a class of numerical semigroups with multiplicity m and embedding dimension e. We call a graph G(S) an S(m,e)-graph if there exists a numerical semigroup S?S(m,e) with V(G(S))={x: x ? g (S)} and E(G(S)) = {xy?x+y?s}, where g(S) denotes the gap set of S. The aim of this article is to discuss the planarity of S(m,e)-graphs for some cases where S is an irreducible numerical semigroup.
