Non-reduced moduli spaces of sheaves on multiple curves
J. -M. Drézet
Some coherent sheaves on projective varieties have a non reduced versal deformation space. For example, this is the case for most unstable rank 2 vector bundles on .…
Reachable sheaves on ribbons and deformations of moduli spaces of sheaves
Jean-Marc Drezet
A primitive multiple curve is a Cohen-Macaulay irreducible projective curve Y that can be locally embedded in a smooth surface, and such that C=Y_red is smooth. In this case, L=I_C…
Reducible deformations and smoothing of primitive multiple curves
Jean-Marc Drézet
A primitive multiple curve is a Cohen-Macaulay irreducible projective curve that can be locally embedded in a smooth surface, and such that is smooth. In this case,…
Fragmented deformations of primitive multiple curves
J. -M. Drezet
A primitive multiple curve is a Cohen-Macaulay irreducible projective curve Y that can be locally embedded in a smooth surface, and such that the associated reduced curve Y_red is…
Courbes multiples primitives et déformations de courbes lisses
Jean-Marc Drezet
A primitive multiple curve is a Cohen-Macaulay scheme Y over the field of complex numbers such that the reduced scheme C=Y_red is a smooth curve, and that Y can be locally embedded…
On the geometry of the moduli spaces of semistable sheaves supported on plane quartics
Jean-Marc Drezet, Mario Maican
We decompose each moduli space of semistable sheaves on the complex projective plane with support of dimension one and degree four into locally closed subvarieties, each subvariety…
