摘要翻译:
设$n=2,3,4,5$和$x$是$\MathBB p^{n+1}$的光滑复射影超曲面。本文给出了$x$次的一个有效下界,使得$x$中的每一个全纯整曲线必须满足一个阶为$k=n=\dim x$的代数微分方程,以及阶为$k>n$的类似下界。此外,对于每一个整数$n\ge2$,我们证明了在$\mathBB p^{n+1}$中光滑超曲面不存在这样的$k<n$级代数微分方程。

英文摘要:
Let $n=2,3,4,5$ and let $X$ be a smooth complex projective hypersurface of $\mathbb P^{n+1}$. In this paper we find an effective lower bound for the degree of $X$, such that every holomorphic entire curve in $X$ must satisfy an algebraic differential equation of order $k=n=\dim X$, and also similar bounds for order $k>n$. Moreover, for every integer $n\ge 2$, we show that there are no such algebraic differential equations of order $k<n$ for a smooth hypersurface in $\mathbb P^{n+1}$.
