Numerical semigroups with multiplicity one more than its width

Abstract: A numerical semigroup S is called Sally type if its multiplicity is one more than its width. In this talk, we will analyze the properties of numerical semigroups of Sally type with embedding dimension $e-1$ and $e-2$ where $e$ denotes the multiplicity. We compute the minimal number of generators of the defining ideal using Hochster's Formula then we determine the minimal generators.
