  1. 1. Infinite dimensional holomorphy in the ring of formal power series : partial differential operators

    Författare :Henrik Petersson; Andrei Khrennikov; Sean Dineen; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infinite dimensional holomorphy; Formal power series; Fourier-Borel transform; Paley-Wiener theorem; Fischer decomposition; Fischer pair; Fock space; Cauchy-Problem; Kergin operator; PDE-preserving; Pseudo-differential operators.; MATHEMATICS; MATEMATIK;

    Sammanfattning : We study holomorphy in the ring of formal power series in an infinite number of variables. Thus we restrict our study to (infinite dimensional) holomorphy on sequence spaces and we show that we obtain a rich theory without requiring any topological structure on the domain space. We make a comprehensive PDO-study for the spaces under consideration. LÄS MER

  3. 2. Residue fixed point index and wildly ramified power series

    Författare :Jonas Nordqvist; Karl-Olof Lindahl; Robert Laurent Benedetto; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wildly ramified power series; residue fixed point index; formal invariant; iterative residue; ramification numbers; non-archimedean; discrete dynamical systems; arithmetic dynamics; periodic points; Nottingham group; Mathematics; Matematik;

    Sammanfattning : This thesis concerns discrete dynamical systems. These are systems where the dynamics is modeled by iterated functions. There are several applications of discrete dynamical system e.g. LÄS MER

  4. 3. Law and Spatial Planning. Socio-legal Perspectives on the Development of Wind Power and 3G Mobile Infrastructures in Sweden

    Författare :Stefan Larsson; Lunds universitets institut för internetstudier; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Law and planning; sociology of law; spatial planning; knowledge-types; expert lay; wind power; 3G mobile telephony; infrastructure; public participation; efficiency; implementation; Sweden.; Law and planning;

    Sammanfattning : This PhD thesis in Spatial Planning argues for the importance of understanding the approaches to knowledge and rationalities embedded in spatially relevant decision-making. It emphasises the significance of seeing law as an empirical object of study for planning and environmental management. LÄS MER

  5. 4. Concept Formation in Mathematics

    Författare :Jörgen Sjögren; Högskolan i Skövde; []
    Nyckelord :HUMANIORA; HUMANITIES; Explication; Power of arithmetical theories; Formal proof; Informal proof; Indispensability; Mathematical realism; Naturvetenskap; Natural sciences; Explication; Power of arithmetical theories; Formal Proof; Informal proof; Indispensability; Mathematical Realism;

    Sammanfattning : This thesis consists of three overlapping parts, where the first one centers around the possibility of defining a measure of the power of arithmetical theories. In this part a partial measure of the power of arithmetical theories is constructed, where “power” is understood as capability to prove theorems. LÄS MER

  7. 5. The Hidden Curriculum. Sexual harassment among university students in Sweden

    Författare :Jack Palmieri; Socialmedicin och global hälsa; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexual harassment; Demand-Control-Support Model; University Students; Power;

    Sammanfattning : Background: The #metoo and #akademiuppropet media campaigns brought into stark relief the ongoing issue of workplace sexual harassment. Previous research shows this to be a pernicious and prevalent problem with severe consequences for individuals and organisations. LÄS MER
