Paramétrisation des courbes multiples primitives
Jean-Marc Drézet
The primitive curves are the multiple curves that can be locally embedded in smooth surfaces (we will always suppose that the associated reduced curves are smooth). These curves ha…
Faisceaux cohérents sur les courbes multiples
Jean-Marc Drézet
Multiple primitive curves have been defined and studied by A. Banica and O. Forster. We introduce new invariants for coherent sheaves on these curves and define quasi locally free…
Espaces abstraits de morphismes et mutations II
J. -M. Drézet
Let E,F be algebraic vector bundles on a projective algebraic variety. Let G=Aut(E)XAut(F), acting on W=Hom(E,F). In this paper new methods of construction of algebraic quotients o…
Fibrés prioritaires génériques instables sur le plan projectif
Jean-Marc Drézet
The structure of the generic prioritary sheaf on the projective plane is given, when it cannot be semi-stable
Espaces abstraits de morphismes et mutations
Jean-Marc Drézet
A transformation of morphisms of sheaves, called mutation, is used to build new moduli spaces of morphisms.
