Curves with stable or semistable normal bundle on Fano hypersurfaces
Abstract
For every and all large enough depending on , there exist curves of genus , degree in a general hypersurface of degree in , or in itself, whose whose normal bundle is stable, as is any sufficiently general full-rank subsheaf of . For , is semi-stable. On general hypersurface of degree in , such that a certain arithmetical condition on holds, there exists an arithmetical progression of values so that curves of degree and genus with semistable normal bundle exist. Previous results were restricted to certain cases with ambient space

Comments
arXiv admin note: text overlap with arXiv:2209.05410 The section on curves on hypersurfaces is new; later version added result on lower-degree hypersurfaces; current version adds results on curve with stable, rather than semistable, normal bundle
