Let H=〈 a, b, c〉 be a numerical semigroup generated by three elements and let R= k [H] be its semigroup ring over a field k. We assume that H is not symmetric and assume that the …

Let N be the set of nonnegative integers. A numerical semigroup H is a subset of N which is closed under addition and N\H is a finite set. We always assume 0∈ H. We define F (H) …

In this paper we study numerical semigroups generated by three elements. We give a characterization of pseudo-symmetric numerical semigroups. Also, we will give a simple …
