Over an infinite field $K$, we investigate the minimal free resolution of some configurations of lines. We explicitly describe the minimal free resolution of "complete grids of lines" and obtain an analogous result about the so-called "complete pseud

Let $\rho_C$ be the regularity of the Hilbert function of a projective curve $C$ in $\mbox {P}^n_K$ over an algebraically closed field $K$ and $\beta_1, \ldots, \beta_{n-1}$ be degrees for which there exists a complete intersection of type ($\beta_1,

In this paper a combinatorial characterization of stable, lex-segment and Borel ideals in P(n) := k[X1, ..., Xn] (assuming chark = 0) is given. The last ones are special monomial ideals, widely studied after the fundamental result of A. Galligo [7] (
In this paper we consider some configurations of lines whose ideals are generated by a product of linear forms. We show that in general these ideals are 1-lifting or pseudo 1-lifting of monomial ideals. This proves also that these ideals are Arithmet

By focusing our attention on the set of monomials outside a given monomial ideal, we tackle the study of the geometric configurations of (reduced) unions of projective linear varieties arising from lifting monomial ideals via a classic lifting proced

Ford≥3g and 1≤s≤[g/2], we study the strataNd, g(s) of degreed genusg spaces curvesC whose normal bundleNC is stable with stability degree (integer of Lange-Narasimhan) σ(NC)=2s. We prove thatNd, g(s) has an irreducible component of the right d
