证明了光滑复代数变体S上的正规函数的零轨迹是代数的,前提是该正规函数在具有扭转奇点的S光滑紧化上扩展为可容许正规函数。这个结果推广了我们之前关于曲线上可容许正规函数的结果[arxiv:math/0604345 [math. ag]]。在最近的预印本[arXiv:0803.2771v2]中,M. Saito也使用了不同的方法获得了它。
We show that the zero locus of a normal function on a smooth complex algebraic variety S is algebraic provided that the normal function extends to a admissible normal function on a smooth compactification of S with torsion singularity. This result generalizes our previous result for admissible normal functions on curves [arxiv:math/0604345 [math.AG]]. It has also been obtained by M. Saito using a different method in a recent preprint [arXiv:0803.2771v2].
