运动超曲面目标的第二大定理
A Second Main Theorem for Moving Hypersurface Targets
摘要:
1979年,B. Shiffman证明了:如果f是C到P^n和D_1的代数非退化全纯映射,.若D_q是P^n中一般位置的超曲面,则D_q的缺陷之和至多为n+1。M. 2004年的Ru。本文在(弱)一般位置上慢动超曲面的情形下,更一般地证明了Shiffman猜想。此外,在相应的第二主要定理中引入了截断,并给出了截断水平的有效估计,从而推广了An-Dongong的一个结果.
英文摘要:
In 1979, B. Shiffman conjectured that if f is an algebraically nondegenerate holomorphic map of C into P^n and D_1,...,D_q are hypersurfaces in P^n in general position, then the sum of the defects is at most n+1. This conjecture was proved by M. Ru in 2004. In this paper, the Shiffman conjecture is proved more generally in the case of slowly moving hypersurfaces in (weakly) general position. Moreover, we introduce a truncation in the corresponding Second Main Theorem, with an effective estimate on the truncation level, thus generalizing a result of An-Phuong.
