Halphen conditions and postulation of nodes
L. Chiantini, N. Chiarli, S. Greco
We give sharp lower bounds for the postulation of the nodes of a general plane projection of a smooth connected curve C in P^r and we study the relationships with the geometry of t…

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…
