Osculating properties of decomposable scrolls Mallavibarrena Martínez de Castro, Raquel Lanteri, Antonio 521.1 scroll (non-normal) osculating space inflectional locus (higher) discriminant locus Astrofísica Osculating spaces of decomposable scrolls (of my genus and not necessarily normal) arc studied and their inflectional loci are related to those of their generating curves by using systematically an idea introduced by Piene and Sacchiero in the setting of rational normal scrolls. In this broader setting the extra components of the second discriminant locus-deriving from flexes-are investigated and a new class of uninflected surface scrolls is presented and characterized. Further properties related to osculation are discussed for (not necessarily decomposable) scrolls.
