关于对数Kobayashi猜想

On the logarithmic Kobayashi conjecture

Gianluca Pacienza, Erwan Rousseau

摘要:

我们研究了对数簇$(\mathbb{P}^n, X)$的双曲性,其中$X$是一个非常一般的度为$d\geq 2n+1$的超曲面(这是Kobayashi猜想所预言的界).利用一个关于(扭曲的)对数向量场层的正性结果,证明了$(\mathbb{P}^n, X)$的任何对数-子簇都是对数-一般型的,给出了$(\mathbb{P}^n, X)$的代数双曲性的一个新证明,并排除了泛度$d$超曲面的补曲面中整曲线的最大秩族的存在性.此外,我们证明了,在紧的情况下,代数双曲的对数簇是一个必要条件的度量。

英文摘要:

We study the hyperbolicity of the log variety $(\mathbb{P}^n, X)$, where $X$ is a very general hypersurface of degree $d\geq 2n+1$ (which is the bound predicted by the Kobayashi conjecture). Using a positivity result for the sheaf of (twisted) logarithmic vector fields, which may be of independent interest, we show that any log-subvariety of $(\mathbb{P}^n, X)$ is of log-general type, give a new proof of the algebraic hyperbolicity of $(\mathbb{P}^n, X)$, and exclude the existence of maximal rank families of entire curves in the complement of the universal degree $d$ hypersurface. Moreover, we prove that, as in the compact case, the algebraic hyperbolicity of a log-variety is a necessary condition for the metric one.
