Asymptotic geometric Tevelev degrees of hypersurfaces
Abstract
Let be a fixed general pointed curve and let be a smooth hypersurface of degree and dimension with general points. We consider the problem of enumerating maps of degree (as measured in the ambient projective space) such that . When is small compared to and is large compared to , , and , these numbers have been computed first by passing to a virtual count in Gromov-Witten theory obtained by Buch-Pandharipande, and then by showing (in work of the author with Pandharipande) that the virtual counts are enumerative via an analysis of boundary contributions in the moduli space of stable maps. In this note, we give a simpler computation via projective geometry.
