Minimal links and a result of Gaeta
Juan Migliore, Uwe Nagel
If is an equidimensional codimension subscheme of an -dimensional projective space, and is linked to by a complete intersection , then we say that is {\e…
Liaison addition and the structure of a Gorenstein liaison class
Robin Hartshorne, Juan Migliore, Uwe Nagel
We study the concept of liaison addition for codimension two subschemes of an arithmetically Gorenstein projective scheme. We show how it relates to liaison and biliaison classes o…
The Hilbert scheme of degree two curves and certain ropes
Uwe Nagel, Roberto Notari, Maria Luisa Spreafico
We study families of ropes of any codimension that are supported on lines. In particular, this includes all non-reduced curves of degree two. We construct suitable smooth parameter…
Normal form for space curves in a double plane
Nadia Chiarli, Silvio Greco, Uwe Nagel]
This note is an attempt to relate explicitly the geometric and algebraic properties of a space curve that is contained in some double plane. We show in particular that the minimal…
Non-degenerate curves with maximal Hartshorne-Rao module
Uwe Nagel
Extending results for space curves we establish bounds for the cohomology of a non-degenerate curve in projective -space. As a consequence, for any given we determine all po…
