  1. 1. 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

  2. 2. 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. 3. Algebras of bounded holomorphic functions

    Författare :Anders Fällström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; holomorphic function; bounded holomorphic function; domain of holomorphy; envelope of holomorphy; Gleason’s problem; convex set; uniform algebra; spectrum; fibers; generalized Shilov boundary; analytic structure; plurisubharmonic function;

    Sammanfattning : Some problems concerning the algebra of bounded holomorphic functions from bounded domains in Cn are solved. A bounded domain of holomorphy Q in C2 with nonschlicht i7°°- envelope of holomorphy is constructed and it is shown that there is a point in Q for which Gleason’s Problem for H°°(Q) cannot be solved.

  4. 4. Holomorphic extension and schlichtness on tube manifolds

    Författare :Suprokash Hazra; Egmont Porten; Cornelia Schiebold; Andreas Lind; Per Åhag; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Envelopes of holomorphy; truncated tube domains; holomorphic extension; Bochner tube; manifold; schlichtness;

    Sammanfattning : We first investigate the holomorphic extension of some classical and accessible classes of domains in $\mathbb{C}^n$ to know to what extent their envelopes are constructive. We give alternative proofs to some of the classical theorems using only first-principle arguments and without involving higher Stein geometry. LÄS MER

  5. 5. Holomorphic functions on polydiscs and measures on the distinguished boundary

    Författare :Linus Bergqvist; Alan Sola; Emmanuel Fricain; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex variables; Holomorphic functions; Polydiscs; matematik; Mathematics;

    Sammanfattning : This thesis consists of four papers, treating holomorphic functions defined on polydiscs, operators acting on spaces of such functions, and related measures on the n-torus. In paper I we study containment of rational inner functions, or RIFs for short, in Dirichlet type spaces on the unit polydisc D^n. LÄS MER
