Abstract

We consider the Cremona transformation Φ~σ~ : ℙ^3^ … → ℙ^3^ which is an extension of the famous Nagata automorphism σ on the affine 3‐space 𝔸^3^. In this paper we shall factorize this Cremona transformation Φ~σ~ explicitly into 8 elementary links according to the Sarkisov Program. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
