  1. 1. Index theory in geometry and physics

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Magnus Goffeng; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect;

    Sammanfattning : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

  2. 2. Price measurement and index construction : some contributions to theory and application

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Jörgen Dalén; Stockholms universitet.; [1995]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Konsumentprisindex;

    Sammanfattning : Four different problems are treated, all concerned with problems arising when compiling price indexes in official statistics. One deals with the computation of so called elementary aggregates, low level indexes for single products, when proper weights for the observations are not available. LÄS MER

  3. 3. Road Safety Development Index Theory, Philosophy and Practice

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ghazwan Al-Haji; Linköpings universitet.; Linköpings universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport; Road Traffic; Sustainability; Road safety; European research cooperation; Civil engineering and architecture; Research on Europe; Public health science; Statistics; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. LÄS MER

  4. 4. Strings, Conformal Field Theory and Noncommutative Geometry

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Keizo Matsubara; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; Conformal field theory; Noncommutative geometry; Star-products; Teoretisk fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : This thesis describes some aspects of noncommutative geometry and conformal field theory. The motivation for the investigations made comes to a large extent from string theory. This theory is today considered to be the most promising way to find a solution to the problem of unifying the four fundamental interactions in one single theory. LÄS MER

  5. 5. Mimetiskt syskonskap En representationsteoretisk undersökning av relationen fiktionsprosa-fiktionsfilm

    Detta är en avhandling från Stockholm : Acta Universitatis Stockholmiensis

    Författare :Christer Johansson; Stockholms universitet.; [2008]
    Nyckelord :HUMANIORA; HUMANITIES; semiotics; narratology; literary theory; film theory; aesthetic theory; representation; medium; fictionality; narrative; meaning; intermediality; iconicity; indexicality; metaphor; narrative perspective; fiction; film; HUMANITIES and RELIGION Aesthetic subjects Literature; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Litteraturvetenskap; litteraturvetenskap; Literature;

    Sammanfattning : The dissertation deals with two different subjects: on the one hand the interrelations of narrative prose fiction and narrative fiction film, on the other hand fictional narration and intermediality as such. The first part discusses the concepts of medium and intermediality, and presents some general theoretical models. LÄS MER
