Halphen conditions and postulation of nodes

Algebraic Geometry 2007-05-23 v1

Abstract

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 the embedding. Strict connections with Castelnuovo's theory and Halphen's theory are shown.
