00925njm 22002777a 4500 dc Lanteri, Antonio author Mallavibarrena Martínez de Castro, Raquel author Piene, Ragni author 2008-03 Let X⊂PN be a scroll over a smooth curve C and let L=OPN(1)|X denote the hyperplane bundle. The special geometry of X implies that certain sheaves related to the principal part bundles of L are locally free. The inflectional loci of X can be expressed in terms of these sheaves, leading to explicit formulas for the cohomology classes of the loci. The formulas imply that the only uninflected scrolls are the balanced rational normal scrolls. 0025-5874 10.1007/s00209-007-0185-5 https://hdl.handle.net/20.500.14352/50536 http://link.springer.com/article/10.1007/s00209-007-0185-5 http://link.springer.com/journal/209 Inflectional loci of scrolls
