A note on rational curves on general Fano hypersurfaces

Algebraic Geometry 2019-02-01 v2

Abstract

We show the Kontsevich space of rational curves of degree at most roughly 222n\frac{2-\sqrt{2}}{2}n on a general hypersurface XPnX\subset \mathbb{P}^n of degree n1n-1 is equidimensional of expected dimension and has two components: one consisting generically of smooth, embedded rational curves and the other consisting of multiple covers of a line. This proves more cases of a conjecture of Coskun, Harris, and Starr and shows the Gromov-Witten invariants in these cases are enumerative.
