Geometry of Rational Curves on Low degree Complete Intersections

15 Jan 2017  ·  Pan Xuanyu ·

For a smooth complete intersection X, we consider a general fiber \mathbb{F} of the evaluation map ev of Kontsevich moduli space \bar{M}_{0,m}(X,m)\rightarrow X^m and the forgetful functor F : \mathbb{F} \rightarrow \bar{M}_{0,m}. We prove that a general fiber of the map $F$ is a smooth complete intersection if $X$ is of low degree... The result sheds some light on the arithmetic and geometry of Fano complete intersections. read more
