关于Miyanishi-Masuda的一个结果
On a result of Miyanishi-Masuda
摘要:
设$X$是一个仿射曲面,它具有唯一的仿射刻划和$\mathbb C^*$ -作用.假设规则有唯一的退化纤维,并且该纤维是不可约的。本文给出了Miyanishi和Masuda的结果:$X$的泛覆盖是由方程$x^my=z^d-1$给出的仿射三维空间中的超曲面,其中$m>1$ .
英文摘要:
Let $X$ be an affine surface admitting a unique affine ruling and a $\mathbb C^*$-action. Assume that the ruling has a unique degenerate fibre and that this fibre is irreducible. In this paper we give a short proof of the following result of Miyanishi and Masuda: the universal covering of $X$ is a hypersurface in the affine 3-space given by the equation $x^my=z^d-1$, where $m>1$.
