具有固定j-不变的椭圆空间曲线的示性数

Characteristic numbers of ellitpic space curves with fixed j-invariant

Dung Nguyen

摘要:

解决了在具有相切条件的射影空间中具有固定j-不变量的椭圆曲线的计数问题。这相当于计算有理节点曲线,并在图像的节点上设置条件。以有效递归的形式给出了解。当周围射影空间的维数不超过5时,我们给出了显式公式。提供了许多数值例子。实现大多数递归的C++程序可以在作者的网页上找到(参见\cite{dn})。

英文摘要:

We solve the problem of counting elliptic curves with fixed j-invariant in projective space with tangency conditions. This is equivalent to couting rational nodal curves with condition on the node of the image. The solution is given in the form of effective recursions. We give explicit formulas when the dimension of the ambient projective space is at most 5. Many numerical examples are provided. A C++ program implementing most of the recursions is available on the author's webpage (see \cite{dn}).
