  2. 21. Strings, Conformal Field Theory and Noncommutative Geometry

    Author : Keizo Matsubara; Anton Alekseev; Edwin Langmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; Conformal field theory; Noncommutative geometry; Star-products; Teoretisk fysik; Physics; Fysik;

    Abstract : 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. READ MORE

  4. 22. On parabolic equations of Kolmogorov-Fokker-Planck type

    Author : Malte Litsgård; Kaj Nyström; Ugo Gianazza; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; degenerate parabolic; ultraparabolic; Lipschitz domain; Dirichlet problem; boundary behaviour; parabolic measure.; Mathematics; Matematik;

    Abstract : In this thesis solutions to Kolmogorov-Fokker-Planck type equations are studied. It consists of a comprehensive summary and four scientific articles.In the first article a potential theory for certain strongly degenerate parabolic operators in unbounded domains of Lipschitz type is developed.

  5. 23. Toric varieties and residues

    Author : Alexey Shchuplev; Mikael Passare; Alekos Vidras; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; toric variety; residue; residue current; integral representation; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : The multidimensional residue theory as well as the theory of integral representations for holomorphic functions is a very powerful tool in complex analysis. The computation of integrals, solving algebraic or differential equations is usually reduced to some residue integral. READ MORE

  6. 24. Models of magnetism in electrical machines

    Author : Gustav Mörée; Mats Leijon; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The magnetic field is a fundamental part of an electrical machine, for establishing the torque and inducing voltages and currents. Then acting as the link between mechanical power and electrical power. This thesis will give a comprehensive study of how magnetism could be modeled. READ MORE

  7. 25. The paramagnetic Meissner effect

    Author : Evie Papadopoulou; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; high-temperature superconductivity; Bi-based compounds; paramagnetic Meissner effect; ageing; disordered magnets; chiral-glass; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. READ MORE
