Hopf Mappings for Complex QuaternionsJohannes WallnerInstitut für Geometrie, Technische Universität Wien, Wiedner Hauptstr.\ 8--10/113, A-1040 Wien, e-mail: wallner@geometrie.tuwien.ac.atAbstract: The natural mapping of the right quaternion vector space $\H^2$ onto the quaternion projective line (identified with the four-sphere) can be defined for complex quaternions $\H\otimes_\R\C$ as well. We discuss its exceptional set, the fiber subspaces, and how the linear automorphism groups of two-dimensional quaternion vector spaces and modules induce groups of projective automorphisms of the image quadrics.
