无穷远处有一个位置的椭圆平面曲线的射影特征

The projective characterization of elliptic plane curves which have one place at infinity

Keita Tono

摘要:

本文考虑在无穷远处有一个位置的光滑仿射椭圆平面曲线。我们将它们与只有一个尖点作为奇点且只在尖点处与无穷远无穷远直线相交的椭圆射影平面曲线等同起来。我们通过严格变换的自相交数来刻画这类曲线,并通过其尖点的最小嵌入分辨来刻画这类曲线。并证明了它们的自交数是所有只有一个尖点的椭圆平面曲线的自交数中的最大值。

英文摘要:

In this paper we consider smooth affine elliptic plane curves having one place at infinity. We identify them with elliptic projective plane curves having only one cusp as their singular points and meeting with the line at infinity only at the cusp. We characterize such curves by the self-intersection number of the strict transform of them via the minimal embedded resolution of their cusp. Furthermore, we prove that the self-intersection number of them is the maximum value among those of all the elliptic plane curves having only one cusp.
