Moduli of Curves and Spin Structures via Algebraic Geometry
Gilberto Bini, Claudio Fontanari
Here we investigate some birational properties of two collections of moduli spaces, namely moduli spaces of (pointed) stable curves and of (pointed) spin curves. In particular, we…
On Waring's problem for partially symmetric tensors
Claudio Fontanari
Here we address a Waring type problem for partially symmetric tensors, extending previous work by Massimiliano Mella in the totally symmetric case of forms. In particular, we provi…
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…
