  2. 1. Holomorphic automorphisms of Danielewski surfaces

    Author : Andreas Lind; Frank Kutzschebauch; Egmont Porten; Frank Wikström; Erik Low; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Danielewski surfaces; holomorphic; automorphisms; Lie groups; Algebra; geometry and mathematical analysis; Algebra; geometri och analys;

    Abstract : In this thesis we define the notion of an overshear on a Danielewskisurface. Next we show that the group generated by the overshears is dense in the component of the identity of the automorphism group. READ MORE

  4. 2. On the automorphism group of Danielewski surfaces

    Author : Andreas Lind; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Automorphisms; Danielewski surfaces; Overshears; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we define the notion of an overshear on a Danielewski surface. We show that the group generated by the overshears is dense (in the compact open topology) in the automorphism group for small degrees of the defining polynomial. It is also shown in the thesis that the overshear group has a structure of an amalgamated product. READ MORE
