In their paper on the embeddings of the line in the plane, Abhyankar and Moh proved an important inequality, now known as the Abhyankar-Moh inequality, which can be stated in terms of the semigroup associated with the branch at infinity of a plane al

The computation of ω-primality has been object of study, mainly, for numerical semigroups due to its multiple applications to the Factorization Theory. However, its asymptotic version is less well known. In this work, we study the asymptotic ω-prim

We propose necessary and sufficient conditions for an integer matrix to be decomposable in terms of its Hermite normal form. Specifically, to each integer matrix, we associate a symmetric integer matrix whose reducibility can be efficiently determine

We introduce an algorithm for computing the ideals associated with some sumset semigroups. Our results allow us to study some additive properties of sumsets.

Weierstrass semigroups are well known along the literature. We present a new family of non- Weierstrass semigroups which can be written as an intersection of Weierstrass semigroups. In addition, we provide methods for computing non-Weierstrass semigr

In this paper we study those submonoids of $$\mathbb {N}^d$$ with a nontrivial pseudo-Frobenius set. In the affine case, we prove that they are the affine semigroups whose associated algebra over a field has maximal projective dimension possible. We

Let $$A \subset \mathbb Z$$ A ⊂ Z be a finite subset. We denote by $${{\,\mathrm{\mathcal {B}}\,}}(A)$$ B ( A ) the set of all integers $$n \ge 2$$ n ≥ 2 such that $$|nA| > (2n-1)(|A|-1),$$ | n A | > ( 2 n - 1 ) ( | A | - 1 ) , where $$nA=A+\cdot

In this work, using the concept of multiple convex body semigroup, we present new families of Buchsbaum semigroups. We characterize Buchsbaum circle and convex polygonal semigroups and we describe algorithmic methods to check such characterizations.

A proportionally modular affine semigroup is the set of nonnegative integer solutions of a modular Diophantine inequality $$f_1x_1+\cdots +f_nx_n \bmod b \le g_1x_1+\cdots +g_nx_n$$ , where $$g_1,\dots ,g_n$$ , $$f_1,\ldots ,f_n\in \mathbb {Z}$$ , an
