Abstract:
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. In this article we give such an $f$ of degree $5$.
Keywords: Cremona group, birational map, automorphisms of surfaces, regularizable.
