The canonical trace of determinantal rings

Antonino Ficarra, Jürgen Herzog, Dumitru I. Stamate +1

We compute the canonical trace of generic determinantal rings and provide a sufficient condition for the trace to specialize. As an application we determine the canonical trace $\m…

The tiny trace ideals of the canonical modules in Cohen-Macaulay rings of dimension one

Jürgen Herzog, Shinya Kumashiro, Dumitru I. Stamate

We study one-dimensional Cohen-Macaulay rings whose trace ideal of the canonical module is as small as possible. In this paper we call such rings far-flung Gorenstein rings. We inv…

Nearly Gorenstein rings arising from finite graphs

Takayuki Hibi, Dumitru I. Stamate

The classification of complete multipartite graphs whose edge rings are nearly Gorenstein as well as that of finite perfect graphs whose stable set rings are nearly Gorenstein is a…

Gröbner-nice pairs of ideals

Mircea Cimpoeaş, Dumitru I. Stamate

We introduce the concept of a Gröbner nice pair of ideals in a polynomial ring and we present some applications.

Graded Bourbaki ideals of graded modules

Jürgen Herzog, Shinya Kumashiro, Dumitru I. Stamate

In this paper we study graded Bourbaki ideals. It is a well-known fact that for torsionfree modules over Noetherian normal domains, Bourbaki sequences exist. We give criteria in te…

Ulrich elements in normal simplicial affine semigroups

Jürgen Herzog, Raheleh Jafari, Dumitru I. Stamate

Let be a normal affine semigroup, its semigroup ring over the field and its canonical module. The Ulrich elements for are those
