论文摘要
贝德福德询问是否存在复杂投影平面的男子式自我地图$ f $,以便对于任何自动形态$ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a \ circ f $并不是与自动形态的共轭。 Blanc给出了这样的$ 6 $ 6 $,并询问是否存在较小学位的例子。在本文中,我们给出了$ 5 $的学位示例。
Bedford asked if there exists a birational self map $f$ of the complex projective plane such that for any automorphism $A$ of the complex projective plane $A\circ f$ is not conjugate to an automorphism. Blanc gave such a $f$ of degree $6$ and asked if there exists an example of smaller degree. In this article we give an example of degree $5$.
