Nearly Gorenstein and almost symmetric properties in shifted numerical semigroups

Dumitru I. Stamate, Francesco Strazzanti

Given the integers $0 < r_{1} < \dots < r_{k}$ , we consider the shifted family of semigroups $M_{n} = ⟨ n, n + r_{1}, \dots, n + r_{k} ⟩$ , where $n > 0$ . For sufficiently large $n$ , we prove tha…

Numerical semigroup tree: type-representation

Jonathan Chappelon, Jorge L. RamÃrez AlfonsÃn, Dumitru I. Stamate

In this paper, we introduce a new depicting of the so-called numerical semigroup tree $T$ . By exploring computationally this improved picture, relying on the type notion o…
