摘要:

本文提出了一种构造具有双有理高斯映射的切向退化曲线的方法,重点关注自同构的非经典性。该方法描述了对Esteves--Homma此类例子的推广。此外,本文给出了一条具有双有理高斯映射的光滑射影曲线,其一般切线包含该曲线的三个或更多点,从而肯定地回答了Kaji提出的问题。

英文摘要:

This paper presents a method of a construction of tangentially degenerate curves with a birational Gauss map, focusing on the non-classicality of automorphisms. This method describes a generalization of Esteves--Homma's example of this kind. In addition, this paper presents a smooth projective curve with a birational Gauss map such that a general tangent line contains three or more points of the curve, which answers a question raised by Kaji in the affirmative.
