Symmetric (Not Complete Intersection) Semigroups Generated by Six Elements,We consider symmetric (not complete intersection) numerical semigroups .., generated by a set of six positive integers {.., …, ..}, ., and derive inequalities for degrees of syzygies of such semigroups and find the lower bound for their Frobenius numbers. We show that this bound may be strengthened if .. satisfies the Watanabe lemma.

Arf Numerical Semigroups with Multiplicity 9 and 10,In this work we give a new characterization of Arf numerical semigroups and use it to parametrize Arf numerical semigroups with multiplicity 9 and 10.

Torsion in Tensor Products over One-Dimensional Domains,Over a one-dimensional Gorenstein local domain ., let . be the endomorphism ring of the maximal of ., viewed as a subring of the integral closure .. If there exist finitely generated .-modules . and ., neither of them free, whose tensor product is torsion-free, we show that . must be local with the same residue field as ..

Syzygies of Numerical Semigroup Rings, a Survey Through Examples,quence of integers in arithmetic progression. Finally, we describe how the resolution is constructed when the semigroup is obtained by gluing of two numerical semigroups of smaller embedding dimension. Along the paper, we provide several non-trivial examples to illustrate our results.
