Minimal free resolutions of projective subschemes of small degree
Uwe Nagel
We discuss the minimal free resolution of an irreducible projective subscheme X. If X is also reduced, we focus on the case when its degree equals two plus the codimension. The set…

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…
