我们给出了光滑射影曲面上朗朗猜想的双曲和复函数域形式,S具有f:S,→,C,orborold基,一条一般类型的orborold曲线。定义奥氏基的纤维多重数是非经典的,可能出现单连通曲面S。此外,一般而言,不可能通过有限覆盖c:S的→S将C本身简化为一般类型的曲线的简单情况。我们保留了郎朗猜想的算术版本,该猜想基于莫德尔猜想的一个或多个版本,ABC猜想的结果,但显然不是福尔廷结果的证明。
We show the hyperbolic and complex function field versions of Lang’s conjecture for smooth projective surfaces S having a fibration f:S→C with orbifold base an orbifold curve of general type. The fibre multiplicities defining the orbifold base are non-classical, and simply-connected surfaces S can occur. Also, it is not possible in general to reduce to the easy case where C itself is a curve of general type by a finite étale cover c:S′→S. We leave open the arithmetic version of Lang’s conjecture, which rests on an orbifold version of Mordell’s Conjecture, consequence of the ABC-conjecture, but apparently not of the proofs of Falting’s result.
