Dilatations of numerical semigroups
Valentina Barucci, Francesco Strazzanti
This paper is focused on numerical semigroups and presents a simple construction, that we call dilatation, which, from a starting semigroup , permits to get an infinite family o…
Families of Gorenstein and almost Gorenstein rings
Valentina Barucci, Marco D'Anna, Francesco Strazzanti
Starting with a commutative ring and an ideal , it is possible to define a family of rings , with , as quotients of the Rees algebra $\oplus_{n \geq 0…
On free resolutions of some semigroup rings
Valentina Barucci, Ralf Fröberg, Mesut Sahin
For some numerical semigroup rings of small embedding dimension, namely those of embedding dimension 3, and symmetric or pseudosymmetric of embedding dimension 4, presentations has…
On differential operators of numerical semigroup rings
Valentina Barucci, Ralf Fröberg
If is a numerical semigroup, we call the ring $\C[S]=\C[t^{d_1},...,t^{d_ν}]$ the semigroup ring of . We study the ring of differential operators on $\C[S]$, a…
Associated graded rings of one-dimensional analytically irreducible rings II
Valentina Barucci, Ralf Fröberg
Lance Bryant noticed in his thesis that there was a flaw in our paper "Associated graded rings of one-dimensional analytically irreducible rings", J. Algebra 304 (2006), 349-358. I…
Type sequences of one-dimensional local analytically irreducible rings
Valentina Barucci, Ioana Cristina Şerban
We extend the notion of type sequence to rings that are not necessarily residually rational. Using this invariant we characterize different types of rings as almost Gorenstein ring…
