A Symmetrization for Almost Symmetric Numerical Semigroups
Manuel Delgado, Meral Süer, Mehmet Yeşil
We characterize almost symmetric numerical semigroups in terms of their associated Young diagrams, showing that almost symmetry is equivalent to a simple numerical identity relatin…
Row-Factorization Matrices in Arf Numerical Semigroups and Defining Ideals
Meral Süer, Mehmet Yeşil
In this paper, we investigate the row-factorization matrices of Arf numerical semigroups, and we provide the full list of such matrices of certain Arf numerical semigroups. We use…
Irreducibility of Arf Numerical Semigroups
Meral Süer
In this paper, we introduce the concept of Arf special gaps of an Arf numerical semigroup, and an algorithm for computing all Arf special gaps of a given Arf numerical semigroup. W…
The catenary degree of the saturated numerical semigroups with prime multiplicity
Meral Süer
In this paper we present the set of saturated numerical semigroups with prime multiplicity. We also characterize the catenary degree of these semigroups that we acquire. The catena…
Symmetric and Pseudo-Symmetric Numerical Semigroups via Young Diagrams and Their Semigroup Rings
Meral Süer, Mehmet Yeşil
This paper studies Young diagrams of symmetric and pseudo-symmetric numerical semigroups and describes new operations on Young diagrams as well as numerical semigroups. These provi…
