摘要

本文证明,若两个从 Cm\mathbb C^mPn(C)\mathbb P^n(\mathbb C) 的亚纯映射 ffgg 对于 (2n+2)(2n+2) 个移动超平面 {ai}i=12n+2\{a_i\}_{i=1}^{2n+2} 具有相同的原像,且重数计算至水平 l0l_0,则映射 f×gf\times g 必在域 R{ai}i=12n+2\mathcal R\{a_i\}_{i=1}^{2n+2} 上代数退化,其中 l0=3n3(n+1)q(q2)l_0=3n^3(n+1)q(q-2)q=(2n+2n+2)q=\binom{2n+2}{n+2}。我们的结果推广了 Fujimoto 关于固定超平面情形的先前结果,并通过给出数 l0l_0 的显式估计改进了其结果。

备注

The result in this version is improved by giving an explicit estimate for the truncation level $l_0$. The method of the proof also is changed, different from the original method. This paper will appear in Complex Variable and Elliptic Equations
