Automorphisms of k*-surfaces
Jürgen Hausen (University of Tübingen)
Abstract: After recalling the necessary background on k*-surfaces, we give a complete description of the automorhpism group of a non-toric rational normal projective k*-surface in terms of isotropy group orders and self intersection numbers of suitable invariant curves. We also discuss the basic ingredients and ideas of the proof.
