摘要翻译:
我们研究了对Kobayashi-Eisenman伪体积形式的对数情形的适应,或者更确切地说,是对Claire Voisin定义的它的变体的适应,她用全纯k-对应来代替全纯映射。对于由复流形X和正交Weil因子组成的对(X,D),我们定义了一个本征对数伪体积形式\phi_{X,D}。然后我们证明了当X是射影的且K_x+D是充足的时\phi_{X,D}是泛型非退化的。这个结果类似于经典的Kobayashi-Ochiai定理。我们还证明了一类对数k平凡对\phi_{X,D}的消失,这是在对数情形下向关于无穷小测度双曲性的Kobayashi猜想方向迈出的重要一步。

英文摘要:
  We study an adaptation to the logarithmic case of the Kobayashi-Eisenman pseudo-volume form, or rather an adaptation of its variant defined by Claire Voisin, for which she replaces holomorphic maps by holomorphic K-correspondences. We define an intrinsic logarithmic pseudo-volume form \Phi_{X,D} for every pair (X,D) consisting of a complex manifold X and a normal crossing Weil divisor, the positive part of which is reduced. We then prove that \Phi_{X,D} is generically non-degenerate when X is projective and K_X+D is ample. This result is analogous to the classical Kobayashi-Ochiai theorem. We also show the vanishing of \Phi_{X,D} for a large class of log-K-trivial pairs, which is an important step in the direction of the Kobayashi conjecture about infinitesimal measure hyperbolicity in the logarithmic case.
