论文摘要
我们讨论了一类二次矢量场的Kahan离散化的奇异性结构，并提供了参数值的分类，以便相应的Kahan映射是可以集成的，尤其是椭圆形曲线不变的铅笔。
We discuss the singularity structure of Kahan discretizations of a class of quadratric vector fields and provide a classification of the parameter values such that the corresponding Kahan map is integrable, in particular, admits an invariant pencil of elliptic curves.
