Abstract

We study rank-2 reflexive sheaves on P3 whose sections are Buchsbaum curves, giving vanishing theorems for the cohomology and bounds and gaps for the existence range of their Chern classes. These results are applied to find Castelnuovo-type theorems for the cohomology of Buchsbaum curves. © 1989
