Abstract

Bedford asked if there exists a birational self map ff of the complex projective plane such that for any automorphism AA of the complex projective plane AfA\circ f is not conjugate to an automorphism. Blanc gave such a ff of degree 66 and asked if there exists an example of smaller degree. In this article we give an example of degree 55.
