  1. 1. Holomorphic automorphisms of Danielewski surfaces

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

    Sammanfattning : 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. LÄS MER

  3. 2. Holomorphic embeddings and applications

    Författare :Sam Lodin; Frank Kutzschebauch; Jörgen Boo; Frank Wikström; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anders´en-Lempert-theory; holomorphic embeddings; Eisenman hyperbolicity; holomorphic group actions; plurisubharmonic extension; analytic polyhedron; MATHEMATICS; MATEMATIK;

    Sammanfattning : In the first part of this thesis we consider the question of the number of equivalenceclasses of holomorphic embeddings of Ck into Cn. We show the existence of holomorphicfamilies of proper holomorphic embeddings of Ck into Cn (0 < k < n−1),such that members of the family are pairwise nonequivalent in a suitable sense. LÄS MER

  4. 3. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

    Författare :Göran Frank; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; unipolar charger; Physics; DMA; differential mobility analyser; DAA; droplet aerosol analyser; fog microstructure; cloud microstructure; fog droplet; cloud droplet; cloud; fysisk instrumentering; fog; Metrologi; physical instrumentation; Metrology; Kärnfysik; Nuclear physics; Fysik; Fysicumarkivet A:2001:Frank;

    Sammanfattning : In this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. LÄS MER

  5. 4. Plastic design of steel bridge girders

    Författare :Frank Axhag; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis assesses the feasibility of a modified plastic design method for continuous steel or composite bridges with slender I-girders. The feasibility evaluation of the design method is closely connected to the moment-rotation relationship of the I-girders at internal supports. LÄS MER
