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…

Comparing Castelnuovo-Mumford regularity and extended degree: the borderline cases
Uwe Nagel
Castelnuovo-Mumford regularity and any extended degree function can be thought of as complexity measures for the structure of finitely generated graded modules. A recent result of…
