On nearly Gorenstein affine semigroups
Raheleh Jafari, Francesco Strazzanti, Santiago Zarzuela Armengou
We describe the canonical module of a simplicial affine semigroup ring and its trace ideal. As a consequence, we characterize when is nearly Gorenst…

The Hilbert-Kunz function of some quadratic quotients of the Rees algebra
Francesco Strazzanti, Santiago Zarzuela Armengou
Given a commutative local ring and an ideal of , a family of quotients of the Rees algebra has been recently studied as a unified approach to the N…

Tangent cones of numerical semigroup rings
Teresa Cortadellas Benitez, Santiago Zarzuela Armengou
In this paper we describe the structure of the tangent cone of a numerical semigroup ring with multiplicity (as a module over the Noether normalizat…
