Un theoreme de Strano montre que si une courbe gauche localement Cohen-Macaulay n'est pas minimale dans sa classe de biliaison, elle admet une biliaison elementaire strictement decroissante. R. Hartshorne a recemment donne une nouvelle preuve de ce r

The aim of this paper is to prove a generalization of a theorem of Rao for families of space curves, which characterizes the biliaison classes of curves. First we introduce the concept of pseudo-isomorphism: let A be a noetherian ring, a morphism f :

Let $A$ be a local noetherian ring and $N$ be a locally sheaf on the projective space $P^3_A$ : one proves easily that there exists a family $C$ of (smooth connected) curves contained in $P^3_A$, flat over $A$, and an integer $h$ such that the ideal

We show that the arithmetically Cohen-Macaulay (ACM) curves of de- gree 4 and genus 0 in P4 form an irreducible subset of the Hilbert scheme. Using this, we show that the singular locus of the corresponding component of the Hilbert scheme has dimensi

Let $A$ be a noetherian ring and $R_A$ be the graded ring $A[X,Y,Z,T]$. In this article we introduce the notion of a triad, which is a generalization to families of curves in ${\bf P}^3_A$ of the notion of Rao module. A triad is a complex of graded $
